The probability that the proportion of flops in a sample of 681 released films would be greater than 8% is ≈ 0.0043 (rounded to four decimal places) or 0.43%.

We shall calculate the probability using the normal approximation to the binomial distribution, since we have a large sample size (n = 681) and the probability of a flop (p = 0.06) is not too close to 0 or 1.

The mean of the binomial distribution = μ = np = 681 x 0.06 = 40.86,

The standard deviation = σ = [tex]\sqrt(np(1-p))[/tex] = [tex]\sqrt(681 * 0.06 * 0.94)[/tex] = 5.08.

We want to find the probability that the proportion of flops in a sample of 681 released films would be greater than 8%, which is equivalent to finding the probability that the sample proportion of flops (p-hat) is greater than 0.08.

To standardize the sample proportion, we can use the formula:

z = (p-hat - p) / [tex]\sqrt(p(1-p)/n)[/tex]

where:

p-hat = sample proportion,

p = the population proportion,

n = the sample size.

Plugging in the values, we get:

z = (0.08 - 0.06) / [tex]\sqrt(0.06 * 0.94 / 681)[/tex] = 2.62

Using a standard normal table or calculator, we can find that the probability of getting a z-score of 2.62 or greater is 0.0043.

Therefore, the probability that the proportion of flops in a sample of 681 released films would be greater than 8% is ≈ 0.0043 or 0.43% (rounded to four decimal places).

Answer:

[tex]\sqrt{\frac{3V}{\pi h} }=r[/tex]

Step-by-step explanation:

The formula for volume of a cone is V = 1/3πr^2h, where V is the volume, r is the radius, and h is the height.

We can express r in terms of the other three parts of the formula by isolating it:

[tex]V=1/3\pi r^2h\\\\3V=\pi r^2h\\\\\frac{3V}{h\pi }=r^2\\ \\\sqrt{\frac{3V}{h\pi } }=r^[/tex]

We can check first by choosing a value for r and h, which will allow us to find a volume.  Then, we can rearrange the numbers using the formula expressing r in terms of the volume, height, and pi

For example, using a radius that is 2 units and height that is 5[tex]V=1/3\pi (2)^2*5\\V=1/3\pi *4*5\\V=20/3\pi \\V=20.94395102[/tex] units will give a volume of 20/3π (i.e., 20.94395102) units:

Now, we can plug in our numbers for the formula expressing r in terms of volume, height, and pi and check that we get a radius of 2:

[tex]\sqrt{(\frac{3*20/3\pi }{5\pi }) } =2\\\sqrt{(\frac{20\pi }{5\pi }) }=2\\ \sqrt{4}=2\\ 2=2[/tex]

Thus, our formula expressing r in terms of V, h, and π is correct

The width of the object is 32 feet.

To find the width of an object given its length and perimeter, we can use the formula for the perimeter of a rectangle: P = 2(length + width).

Given that the length is 54 feet and the perimeter is 172 feet, we can substitute these values into the formula:

172 = 2(54 + width)

Dividing both sides of the equation by 2, we get:

86 = 54 + width

Subtracting 54 from both sides, we find:

The probability of the component failing within the first 6 months is approximately 0.3935 or 39.35%.

For the probability of the component failing within the first 6 months, we need to find the cumulative distribution function (CDF) of the Gamma distribution with parameters α = 2 and λ = 2, and evaluate it at t = 0.5 years (6 months).

Hence, The CDF of a Gamma distribution with parameters α and λ is given by:

F(t) = γ(α, λt) / Γ(α)

where γ is the lower incomplete Gamma function and Γ is the Gamma function.

Plugging in α = 2 and λ = 2, we get:

F(t) = γ(2, 2t) / Γ(2) = (1 - e^(-2t))(2t)

To find the probability of the component failing within the first 6 months (t = 0.5 years), we simply evaluate the CDF at t = 0.5:

F(0.5) = (1 - e^(-2(0.5)))(2(0.5))

= 0.3935

A chance that the sample mean income level falls between $49,000 and $51,000 is 39.38%.

Based on the given information, we know that the population mean (average income) in New York City is $50,000 and the population standard deviation is $10,000.

If we randomly sample 625 people and ask them what their income level is, we can use the central limit theorem to approximate the distribution of sample means.

The central limit theorem states that for a large enough sample size (in this case, n = 625), the distribution of sample means will be approximately normal, regardless of the distribution of the population.

To calculate the mean and standard deviation of the sample means, we can use the following formulas:

Mean of sample means = population mean = $50,000
Standard deviation of sample means = population standard deviation / square root of sample size
= $10,000 / sqrt(625)
= $10,000 / 25
= $400

Therefore, the mean income level of the 625 people in the sample is expected to be $50,000, and the standard deviation of the sample means is $400.

Using this information, we can also calculate the probability of certain income levels in the sample. For example, we can calculate the probability that the sample mean income level is between $49,000 and $51,000:

Z-score for lower limit = (49,000 - 50,000) / 400 = -0.25
Z-score for upper limit = (51,000 - 50,000) / 400 = 0.25

Using a standard normal distribution table or calculator, we can find the probability of a Z-score between -0.25 and 0.25 to be approximately 0.3938.

Therefore, there is a 39.38% chance that the sample mean income level falls between $49,000 and $51,000.

When performing a statistical test, such as the Chi-Square test, the p-value is a crucial component in determining the significance of the data compared to the null hypothesis. The p-value represents the probability of observing the given data, or more extreme results, assuming the null hypothesis is true. In general, a p-value threshold of 0.05 is used to determine statistical significance.

If the calculated p-value is less than or equal to 0.05, it indicates that the observed data significantly differ from what is expected under the null hypothesis. This means that there is a less than 5% chance of obtaining the observed data if the null hypothesis were true. Consequently, researchers often reject the null hypothesis in favor of the alternative hypothesis when the p-value is less than or equal to 0.05.

However, it is essential to note that the choice of the significance level is subjective and may vary depending on the field or specific study. In some cases, a more stringent threshold, such as 0.01, might be required to minimize the chances of false positives, while in other situations, a more lenient threshold, such as 0.10, may be acceptable.

In summary, a p-value of 0.05 or less typically indicates that the data differ significantly from what is expected under the null hypothesis in a statistical test like the Chi-Square test. However, the chosen threshold for significance may vary depending on the specific context and research objectives.

The correct option is (a) MS. Because ANOVA terminology, the term used for variance is MS.

How to used MS within in ANOVA terminology ?

ANOVA terminology is a statistical method used to compare the means of two or more groups. The method partitions the total variability of the data into different sources of variation, such as the variation between groups (treatments) and the variation within groups (error). The goal is to determine whether the differences between the means of the groups are statistically significant, or whether they are due to chance.

In ANOVA, the total variability is decomposed into three types of sums of squares (SS):

SS total: the total sum of squares of the deviation of each data point from the overall mean of all data points.

SS between: the sum of squares of the deviation of each group mean from the overall mean.

SS within: the sum of squares of the deviation of each data point from its group mean.

The degrees of freedom (df) associated with each sum of squares are calculated based on the sample size and the number of groups.

To test whether the differences between the group means are statistically significant, the F-ratio is calculated as the ratio of the variance between groups (MS between) to the variance within groups

(MS within):

F = MS between / MS within

If the F-ratio is greater than the critical value at a chosen level of significance, the null hypothesis of no difference between the group means is rejected, and it is concluded that there is a significant difference between at least two of the group means.

MS between and MS within are both mean squares (MS), which represent the variance associated with the between-group and within-group variability, respectively. They are calculated by dividing the corresponding SS by their respective degrees of freedom.

The area of the jogging path is 4L + 4W + 16 square meters.

To find the area of the jogging path in the park, we need to know the dimensions of the rectangle. Let's assume that the length of the rectangle is L and the width is W. Then, the new dimensions of the rectangle, including the jogging path, would be (L+4) and (W+4), since the jogging path is 2 meters wide on both sides of the rectangle.

Therefore, the area of the jogging path would be the difference between the area of the larger rectangle and the area of the original rectangle. The area of the larger rectangle is:

(L+4) × (W+4)

And the area of the original rectangle is:

L × W

So the area of the jogging path would be:
