You want to know if an employee's opinion about an organization is the same as the opinion of that employee's boss. You collect data from 18 employee-supervisor pairs and code the difference scores so that positive scores indicate that the employee has a higher opinion and negative scores indicate that the boss has a higher opinion (meaning that difference scores of 0 indicate no difference and complete agreement). You find that the mean difference score is Xy = -3.15 with a standard deviation of Sp = 1.97. Test this two- tailed hypothesis at the a = 0.01 level. O Fail to reject (retain) the null. There is no evidence the employees' opinions are lower than the supervisors. O Fail to reject (retain) the null. There is evidence the employees' opinions are lower than the supervisors. O Reject the null. There is evidence the employees' opinions are lower than the supervisors. O Reject the null. There is no evidence the employees' opinions are lower than the supervisors.Determine whether to reject or fail to reject the null hypothesis in the following situation: t(40) = 2.49, a = 0.01. O Rject the null hypothesis. O Fail to reject (retain) the null hypothesis
