1)

A researcher is studying the heights of men with a certain medical condition. She collects a sample of 37 such men and finds the mean height of the sample to be x̄ = 66.9 inches. Assume that the standard deviation of heights of men with the condition is the same as that of the general population, σ = 2.8 inches.

a) Find a 99% confidence interval for the true mean height of the population of mean with this condition.

b) Provide the right endpoint of the interval as your answer.

Round your answer to 2 decimal places.

    Suppose a random sample of 200 20-year-old men is selected from a population and their heights and weights are recorded. A regression of weight on height yields \ Weight = −99.41 + 3.94(Height),R2 = 0.81,SER = 10.2 SE for beta_hat_0=(2.15), SE for beta_hat_1= (0.31) where Weight is measured in pounds and Height is measured in inches. Two of your classmates differ in height by 2 inches. Construct a 99% confidence interval for the differences in weights.
