Use the sample data and confidence level given below to complete parts a through d.
A research institute poll asked respondents if they felt vulnerable to identity theft. In the poll, n=929 and x=515 who said yes. Use a 95% confidecne level.
A. find the best point of estimate of the population of portion p.
B. Identify the value of the margin of error E.
E= round to four decimal places as needed.
C. Construct the confidence interval.
_ < p <_ round to three decimal places.
D. Write a statement that correctly interprets the confidence interval.

Using the information given and the z-distribution, it is found that:

a) The point estimate of the population proportion is 0.5544.

b) The margin of error is: 0.0320.

c) The interval is: (0.5224, 0.5864).

d) The interpretation of the interval is: we are 95% sure that the true population proportion is between 0.5224 and 0.5864.

A confidence interval of proportions has the bounds given by the rule presented as follows:

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which the variables used to calculated these bounds are listed as follows:

The confidence level is of 95%, hence the critical value z is the value of Z that has a p-value of [tex]\frac{1+0.95}{2} = 0.975[/tex], so the critical value is z = 1.96.

From the sample, the sample size and the point estimate are given as follows:

[tex]n = 929, \pi = \frac{515}{929} = 0.5544[/tex]

The margin of error is given by:

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

[tex]M = 1.96\sqrt{\frac{0.5544(0.4456)}{929}}[/tex]

M = 0.0320.

The interval is the point estimate plus/minus the margin of error, hence:

Imagine a scatterplot of a class of 20 students showing the relationship between SAT scores on
the x axis and class grade on the y axis, with 19 of the dots showing a clear positive linear
relationship going from the bottom left to the upper right. However, the 20th student (who scored
very high on the SAT) hasn't been going to class or doing the homework and so is flunking the
class. Thus, that datapoint is by itself in the bottom right hand corner of the scatterplot. What
would be the effect on the correlation between SAT and grades if the slacker dropped the class and
his datapoint was deleted?
A. The correlation coefficient (r) would increase.
B. The correlation coefficient (r) would decrease.
C. The correlation coefficient (r) would not change.
D. It is impossible to know.
