Question

An executive believes that no more than 80% of the company's employees take all of their vacation days. In a sample of 210 members, 158 employees took all of their vacation days. Therefore, the p-value is 0.0422. When testing the executive's (using a 5% level of significance), what can you conclude concerning the null hypothesis? Reject the null hypothesis Fail to reject the null hypothesis In a sample of 61 business trips taken by employees in the HR department, a company finds that the average amount spent for the trips was exist1480 with a standard deviation of exist450. In a sample of 101 tips taken by the employees in the sales department is exist1650 with a standard deviation of exist550. When testing the hypothesis (at the 5% level of significance) that the average amount spent on trips taken by the sales department are higher than those taken by the HR department what is the null and alternative hypotheses? (please write out the null and alternative hypotheses below AND on your scratch work... failure to do BOTH will result in)

Explanation / Answer

4)

since p-value is less than level of significance 0.0422 < 0.05

we reject the null hypothesis

hence option A) is correct
