10. Consider the same population introduced in Question 7, in which the population is normally distributed with mean =77 mm Hg and standard deviation =11.6 mm Hg. For the following 2 questions, suppose that you select repeated samples of size 40 from the population and calculate the mean for each sample. What should the mean of the sample means be? Hint: Think Central Limit Theorem. Refer to question 10, what should the standard deviation of the sample means (standard error) be? Use 2 decimal places.
