The mean scores of a random sample of 17 students who took a special test is 83.5. If the standard deviation of the scores is 4.1, and the sample comes from normal population, find the point and the interval estimates of the population mean adopting a confidence level of 90%.

Point estimate = _____

Interval estimate = _____

Answer #1

Solution:- Given that n = 17, x = 83.5, sd = 4.1

=> point estimate = 83.5

=> interval estimate = (81.764,85.236)

Suppose that 300 statistics students each took a random sample (with replacement) of 50 students at their college and recorded the ages of the students in their sample. Then each student used his or her data to calculate a 90 % the confidence interval for the mean age of all students at the college. How many of the 300 intervals would you expect to capture the true population mean age, and how many would you expect not to capture the...
