To facilitate a more convenient reporting, we have separated this question into two parts below: i. Report the z-score corresponding to 10.5 percent to 2 decimal places. ii. Report the final probability to 4 decimal places. (d) Find the probability that the mean return for the 38 sampled stocks is between 11.25 and 13.5 percent. To facilitate a more convenient reporting, we have separated this question into two parts below: i. Report the z-scores corresponding to 11.25 percent and 13.25 percent to two decimal places. ii. Report the final probability to 4 decimal places. 3 (e) What is the value of the sample mean that corresponds to the 75th percentile for the sam- pling distribution of the sample mean based on a sample of 38 stocks? Compute this value and report the answer to two decimal places.Calender + Fall Semester X ENGLISH G Describing the X Homework He X Quiz: Homewc X Homework As X [Solved] New X Homework As X Sampling Dist X + C canvas.iastate.edu/courses/92848/pages/homework-assignment-4?module_item_id=4684205 * OM Update : + Planner Writing Journal Canvas Outlook Homework Assignment 4.pdf & Download @ Info X Close Page 3 > of 7 ZOOM + 2. New York Stock Exchange. Suppose that the percentage returns for a given year for all stocks listed on the New York Stock Exchange follows a non-normal distribution with mean u = 12 percent and a standard deviation of o = 9.25 percent. (a) Consider drawing a random sample of n = 9 stocks from the population of all stocks and calculating the mean return of the nine sampled stocks. Remember that we can think of the observed sample mean, x, as a single draw from a distribution that relates to the random variable X. We call this distribution the sampling distribution of the sample mean. i. What is the mean of the sampling distribution of the sample mean when n = 9? (Do NOT round your answer.) ii. What is the standard error of the sampling distribution of the sample mean when n = 9? (Report to the nearest two decimal places.) iii. What is the shape of the sampling distribution of the sample mean when n = 9? (Choose one) . Normal . Approximately Normal . Neither of the two choices above iv. Given the tools we have learned in class, can you find the probability that the mean return of the 9 sampled stocks is less than 30 percent? (Choose one) Yes or No (b) Now consider drawing a random sample of n = 38 from the population of all stocks. Specify the sampling distribution of the sample mean when n = 38. i. What is the mean of the sampling distribution of the sample mean when n = 38? (Do NOT round answer.) ii. What is the standard error of the sampling distribution of the sample mean when n = 38?
