Independent random samples were selected from two quantitative populations, with sample data given below. Using thep-value approach for the data given below, is there sufficient evidence to show that1

is larger than2

at the 1% level of significance?

n1=n2= 50,x1=125.3,x2=123.8,s1=5.5,s2=6.9

Use the value of the test statistics1.20to calculate thep-value for the test. (Round your answer to four decimal places.)

p-value =

State your conclusion.

H0is not rejected. There is insufficient evidence to indicate that the mean forpopulation 1is larger than the mean forpopulation 2.

H0is not rejected. There is sufficient evidence to indicate that the mean forpopulation 1is larger than the mean forpopulation 2.

Is this result consistent with the one obtained using the critical value approach, with= 0.01?
