Independent random samples were selected from two quantitative populations, with sample data given below. Using the p-value approach for the data given below, is there sufficient evidence to show that 1 is larger than 2 at the 1% level of significance?
n1 = n2 = 50, x1 = 125.1, x2 = 123.6,
s1 = 5.7, s2 = 6.9
Use the value of the test statistics 1.19 to calculate the p-value for the test. (Round your answer to four decimal places.)
p-value =
State your conclusion.
- H0 is not rejected. There is sufficient evidence to indicate that the mean for population 1 is larger than the mean for population 2.
- H0 is rejected. There is sufficient evidence to indicate that the mean for population 1 is larger than the mean for population 2.
- H0 is not rejected. There is insufficient evidence to indicate that the mean for population 1 is larger than the mean for population 2.
- H0 is rejected. There is insufficient evidence to indicate that the mean for population 1 is larger than the mean for population 2.
Is this result consistent with the one obtained using the critical value approach, with = 0.01?
- Yes
- No
