12. In a sample of 50 business trips taken by employees in the HR department, a company finds that the average amount spent for the trips was $1450 with a standard deviation of $450. In a sample of 90 trips taken by the employees in the sales department is $1650 with a standard deviation of $550. When testing the hypothesis (at the 10% level of significance) that the varianceof the amount spent on trips is significantly larger in one department than the other, if the p-value 0.063, what is your conclusion concerning the null hypothesis Reject the null hypothesis Fail to reject the null hypothesis
