At the end of one month the department is interested in checking the claims of the study. The department selects a random sample of employees and collects information on the number of hours they have spent meditating (X) and they score their performances based on their revenue contribution to the company (Yi). They estimate the following regression function:
^Y = 45.63 + 3.60X
where ^Y denotes the predicted value of the score obtained by the individual and X denotes the number of hours they spend meditating. The SE(^P1) is 1.01. The HR department wishes to test whether or not meditating increases the performance of their employees. Which of the following are the null and the alternative hypotheses of the test the department wishes to conduct?
A. H0: beta1 = 0 vs H1: beta1 is not equal to 0.
B. H0: beta1 = 0 vs H1: beta1 < 0.
C. H0: beta1 = 3.60 vs H1: beta is not equal to 3.60.
D. H0: beta1 = 0 vs H1: beta1 > 0.
A. The value of the t-statistic associated with the test the HR department wishes to conduct is.
At the 5% significance level, the department wouldthe null hypothesis.
