If both variable in a correlational study are non-numerical, the data can be organized in a matrix and then analyzed using a Chi-square hypothesis test.

A correlational study design investigates relationships between two variables (or more) without the researcher controlling or manipulating any of them.

Chi-square test for hypothesis tests about whether your data is as expected. The basic idea behind the test is to compare the observed values in your data to the expected values that you would see if the null hypothesis is true.

The Chi-square statistic compares the size of any discrepancies between the expected results and the actual results, given the size of the sample and the number of variables in the relationship.

The percentage that the number of individual packages increased by in the newly designed box is 40%

To find the percentage increase, you first need to find the increase in the number of individual packages in the newly designed box.

This increase is:

= Newly designed box quantity - old box of snacks

= 28 - 20

= 8 individual packages

The percentage increase would then be:
= Increase in packages / Number of packages in old box of snacks

The 99% confidence interval for the population mean is (20.6568, 29.3432)

In statistics, a confidence interval describes the likelihood that a population parameter would fall between a set of values for a given percentage of the time. Confidence ranges that include 95% or 99% of anticipated observations are frequently used by analysts. Therefore, it can be concluded that there is a 95% probability that the true value falls within that range if a point estimate of 10.00 is produced from a statistical model with a 95% confidence interval of 9.50 - 10.50.

Given:

Sample size = 21

Since 11 times 4 = 44, you can multiply your 5 by 4 to get 20.

The area of square abcd is  be parallel lines passing through $a$, $b$, $c$, respectively is the 433.

Squares are quadrilaterals with four congruent aspects and four proper angles, and additionally they have units of parallel aspects. Parallelograms are quadrilaterals with units of parallel aspects. Since squares have to be quadrilaterals with units of parallel aspects, then all squares are parallelograms.

Here we have the values the distance between lines a and b is 12, and the distance between lines b and c is 17.

The distance is 12 and 17

Step-by-step explanation:

Using Counting principle,

The black center square contains total 330 small squares.

We start with lowest one i.e 1 × 1

Let’s consider any one face out of six faces of cube ,

as one face of grid or cube is made up of 25 small squares.

If we are facing difficulty in visualising then

simply we draw a 5× 5 board on paper, just as seen in above picture :

and now check 2× 2 squares.

By using R1, R2 and all columns we shall be able to draw 4 such blocks.

Again, R2,R3 and R3, R4 and R4,R5 we can easily draw 4 squares each cash .

Thus, total square count of 2× 2 squares will be

= 16

similarly, we do it for 3× 3 and 4×4 and we will get 9 & 4 respectively.

For final one 5× 5 there is one big square

So, total squares for one face will be

= 25+16+9+4+1=55

Since, there are 6 such faces for a cube then

=>55× 6= 330

Hence, total squares contain the black center square is 330.

A 95% confidence interval for population proportion p is (0.5336, 0.7213).

Given,

One difficulty in measuring the nesting success of birds is that the researchers must count the number of eggs in the nest, which is disturbing to the parents. Even though the researcher does not harm the birds, the flight of the bird might alert predators to the presence of a nest. To see if researcher activity might degrade nesting success, the nest survival of 102 nests that had their eggs counted, was recorded. Sixty-four of the nests failed (i.e. the parent abandoned the nest.)

To find,

Assuming that it is reasonable to regard the 102 nests in the sample as representative of the population of nests for which the eggs have been counted, construct and interpret a 95% confidence interval for the proportion of nests that have eggs counted that are then abandoned;

n = 102

x = 64

Point estimate = sample proportion = [tex]\hat p[/tex] = x / n = 64/102 =0.627

1 - [tex]\hat p[/tex] = 1 - 0.627 = 0.373

[tex]Z\alpha/2[/tex] = 1.96

The margin of error = E

                         [tex]= Z\alpha / 2 * \sqrt((\hat p * (1 - \hat p)) / n) = 1.96 * (\sqrt(0.627*(0.373) /102 ) = 0.0934[/tex]

A 95% confidence interval for population proportion p is;

[tex]\hat p[/tex]  - E < p <  [tex]\hat p[/tex]  + E

0.627 - 0.0934 < p < 0.627 + 0.0934

0.5336 < p < 0.7213

Using the Real rate of return,

the real value of the invetment at the end of one year is $1058.

Real rate of return:

The real rate of return is the present value of the return on investment after taxes and inflation.

By considering the expected inflation rate and the effective interest rate in the compounding interval, we can derive the real interest rate.

Real Rate Of Return Formula,

Real rate of return = [( 1+ Nominal rate )/(1+ inflation rate) ] - 1

The principal amount of investment by Mr.X ( A)

= $1,000

The nominal or current rate of interest (i)= 10%

The rate of inflation ( π )= 4%

pulging all the values in above formula we get,

rate of return (R) =[ ( 1 + i ) /(1+π)] - 1

=> R =[ (1+0.1 )/(1+0.04) ] - 1 = (1.1 / 1.04 ) - 1

=> R = 0.05769(approx.)

=5.8%(approx.)

so, real rate of return = 5.8%

Real value of investment after a year = principle amount (A) + { real rate return × principle amount}

Real value of investment =$1,000+{5.8%×$1,000}

=$1,000+$58

=$1,058

Hence, real value of investment at the end of year is $1,058.

Step-by-step explanation:

sin(30)=AB/AC

=> AB=Sin(30)*AC

sin(30)=0.5

=>AB=0.5*24=15

sin(30)=AB/AC

=> AB=Sin(30)*AC

sin(30)=0.5

=>AB=0.5*36=18

Answer:

part a: AB = 12cm

part b: AB = 18cm

Step-by-step explanation:

sin(angle)=OPP/HYP

sine of an angle is a ratio of two sides of a right triangle. For sine, the ratio is the opposite side over the hypotenuse. In part a the marked angle is 30° and AB is the opposite side. The hypotenuse is given, 24cm.

So the sin 30°

= opp/hyp

= AB / 24

also given is the fact that sin30°=.5

Substitute that into our equation also.

sin30° = AB/24

.5 = AB/24

multiply both sides by 24.

.5×24 = AB

12 = AB

AB is 12 cm.

Part b is an identical calculation except the hypotenuse is 36cm.

sin30° = AB/36

.5 = AB/36

.5×36 = AB

18 = AB

AB is 18cm.

Using the Equivalent Taxable yield formula ,

the equivalent Taxable yield for a taxpayer is 10.75%.

Equivalent Taxable yield :

Tax-equivalent yield is determined by taking the yield of a tax-exempt bond and dividing it by one minus an investor's federal income tax bracket.

Tax-equivalent yield is a way to measure the return on a taxable bond or other investment to make it equal to the return associated with a tax-exempt bond or investment.

Formula:

Tax-equivalent yield = interest rate ÷ (1 – tax rate)

We have given that

Marginal tax bracket or tax rate = 33%

currently priced yield = 7.2 %

Equivalent taxable yield = Yield / ( 1 - Tax% )

= 7.2% / ( 1 - 33% )

= 0.072 /(1-0.33)

Answer: 3 negative residuals and 5 positive residuals

Step-by-step explanation:  When the observed number is lower than the predicted number then this is an example of a negative residual. The tricky thing is this doesn't make much sense you would think that this would be a positive residual but it's not to that's something you need to remember!

example

observed number: 10

predicted number: 10.5

this is a negative residual and it's the opposite for the positive residual

The data set has 2 negative residuals and 6 positive residuals. which is the correct answer would be an option (A).

A residual is a difference between the observed value and the predicted value for a given data point. The sign of the residual indicates whether the predicted value is above or below the observed value.

The table defines the observed data values and the corresponding predicted values, based on a regression line of fit.

Observed    Predicted

9                    7.77

12                    12.87

12                    11.17

15                    14.57

17                    16.27

24                    24.77

28                    26.47

33                    31.57

In this case, the residuals for the data points would be calculated as follows:

Observed value - Predicted value = Residual

9 - 7.77 = 1.23 (positive)

12 - 12.87 = -0.87 (negative)

12 - 11.17 = 0.83 (positive)

15 - 14.57 = 0.43 (positive)

17 - 16.27 = 0.73 (positive)

24 - 24.77 = -0.77 (negative)

28 - 26.47 = 1.53 (positive)

33 - 31.57 = 1.43 (positive)

Based on these calculations, there are 2 negative residuals (-0.87 and -0.77) and 6 positive residuals (1.23, 0.83, 0.43, 0.73, 1.53, and 1.43).
