16. Data are collected on the number of tourists to a city (thousand) and total tourism revenue ($million) for a sample of 20 cities in US. According to the following output, what is the 99%confidence interval of regression slope for this regression model?

Regression Analysis: Tourism Revenue ($million) versus Tourists (thousand)

The regression equation is: Tourism ($million) = 15.747 + 0.32479 Tourists (thousand)

Predictor               Coef    SE Coef

Constant              15.747      2.455

Tourists (thousand)  0.32479   0.07547

S = 1.7386   R-Sq = 63.4%

Regression Analysis with a Minitab output Assume that your company owns multiple retail outlets in cities across the United States. You conduct a study to determine if daily sales levels (in hundreds of dollars) can be predicted by the number of competitors that are located within a one-mile radius of each location and city population (in thousands of people). Therefore, the dependent variable is SALES and the two independent variables are NUMBER OF COMPETITORS and CITY POPULATION. Your research team...
