25. The general manager of a chain of furniture stores believes that experience is the most important factor in determining the level of success of a salesperson. To examine this belief she records last month's sales (in $1,000s) and the years of experience of 10 randomly selected salespeople. These data are listed below. Salesperson Years of Experience Sales 1 7 2 3 4 5 6 7 8 9 10 0 2 10 3 8 5 12 7 20 15 9 20 15 18 14 20 17 30 25 Determine the least squares regression line. Interpret the value of the slope of the regression line. Estimate the monthly sales for a salesperson with 16 years of experience. Conduct a test of the population slope to determine at the 5% significance level whether a linear relationship exists between years of experience and sales. Determine the coefficient of determination and discuss what its value tells you about the two variables.
