8) In a sample of 80 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 60 trips taken by the employees in the sales department is $1650 with a standard deviation of $700. 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, if the p-value is 0.027 then what is your conclusion concerning the null hypothesis?

select

a) reject null hypothesis

b) fail to reject null hypothesis
