Describe the sampling distribution of \( \hat{p} \). Assume the size of the population is 20,000 . \( n=700, p=0.6 \) A. Approximately normal because \( n \leq 0.05 \mathrm{~N} \) and \( n p(1-p)<10 \). Choose the phrase that best describes the shape of the sampling distribution of \( \hat{p} \) below. C. Not normal because \( n \leq 0.05 \mathrm{~N} \) and \( n p(1-p) \geq 10 \). Dotrmal because \( n \leq 0.05 \mathrm{~N} \) and \( n p(1-p)<10 \). Determine the mean of the sampling distribution of \( \hat{p} \). \( \mu_{p}=\square \) (Round to one decimal place as needed.)

In a class, there are 750 learners in 1st year, 420 learners in 2 nd year. Draw a pie graph to represent the numbers of learners in these groups.

\#2 A survey was taken comparing the number of hours per week students spent studying and their performance on an exam. If a linear regression was performed and the correlation coefficient was -0.017 , what can be said about these results? a. As the number of hours spent studying increases, student exam performances will likely not change. b. As the number of hours spent studying inrceases, student exam performances will probably increase. c. As the number of hours spent studying increases, student exam performances will probably decrease. d. There is little evidence of a linear relationship between the number of hours spent studying and student exam performances.

\#7 A set of data has correlation coefficient \( r \). For which value of \( r \) would the average magnitude of the residuals be the smallest? a. \( r=-0.034 \) b. \( r=0.472 \) c. \( r=0.908 \) d. \( r=0.952 \)
