Use the information below to answer the following question(s).
Cars.com would like to use simple regression to predict the selling price of a used car, in thousands of dollars, based on the age of the car in years. A random sample of used cars was selected and the result of the regression analysis is shown below.
Which one of the following statements is true using α = 0.05?
▸ Because the 95% confidence interval for the population slope includes zero, we can reject the null hypothesis and conclude that there is a relationship between the age and selling price of a used car.
▸ Because the 95% confidence interval for the population slope includes zero, we fail to reject the null hypothesis and conclude that there is a relationship between the age and selling price of a used car.
▸ Because the 95% confidence interval for the population slope does not include zero, we fail to reject the null hypothesis and conclude that there is a relationship between the age and selling price of a used car.
▸ Because the 95% confidence interval for the population slope does not include zero, we can reject the null hypothesis and conclude that there is a relationship between the age and selling price of a used car.
