Management would like to use simple regression analysis to estimate monthly car sales using the number of years of sales experience. Which one of the following statements describes the results of the hypothesis test that the population correlation coefficient is greater than zero using
α = 0.05?
▸ Because the test statistic is greater than the critical value, we can reject the null hypothesis and conclude that the population correlation coefficient is greater than zero.
▸ Because the test statistic is greater than the critical value, we fail to reject the null hypothesis and conclude that the population correlation coefficient is greater than zero.
▸ Because the test statistic is less than the critical value, we fail to reject the null hypothesis and conclude that the population correlation coefficient is not greater than zero.
▸ Because the test statistic is less than the critical value, we can reject the null hypothesis and conclude that the population correlation coefficient is not greater than zero.
