Question

The data below are the temperatures on randomly chosen days during the summer and the number of employee absences at a local company on those days. Test the claim, at the $\alpha = 0.05$ level of significance, that a linear relation exists between the two variables, given that $\hat{y} = 0.449x - 30.27$. Temperature, x | 72 | 85 | 91 | 90 | 88 | 98 | 75 | 100 | 80 | Number of absences, y | 3 | 7 | 10 | 10 | 8 | 15 | 4 | 15 | 5 |

Step 1

The null hypothesis (H0) is that there is no linear relationship between the temperature and the number of employee absences. The alternative hypothesis (Ha) is that there is a linear relationship between the temperature and the number of employee absences. H0: Show more…
