We have a dataset that records relevant variables for studying incidence and mortality of skin cancer for several locations. We fit a linear model to predict mortality (deaths per 10 million people) from latitude (degrees) and want to predict the mortality rate for a location at 40 degrees latitude. The 95% confidence interval for μY given xnew = 40 is (144.562, 155.606). Explain what this means.

3. Studies show that exercising can help prevent heart disease. Therefore, a researcher decided to determine if cholesterol concentration was related to time spent watching TV in otherwise healthy 45 to 65-year-old men (an at-risk category of people). To carry out the analysis, the researcher recruited 100 healthy male participants between the ages of 45 and 65 years old. The amount of time spent watching TV (the independent variable, time_tv) and cholesterol concentration (the dependent variable, cholesterol) were recorded for all 100 participants. You can find out the STATA outcome below. regress cholesterol time_tv Source SS df MS Number of obs = 100 F(1, 98) = 17.47 Model 5.04902329 1 5.04902329 Prob > F = 0.0001 Residual 28.3220135 98 .289000137 R-squared = 0.1513 Total 33.3710367 99 .337081179 Adj R-squared = 0.1426 Root MSE = .53759 cholesterol Coef.
