Question

Given below are the analysis of variance results from a Minitab display. Assume that you want to use a 0.05 significance level in testing the null hypothesis that the different samples come from populations with the same mean. What can you conclude about the equality of the population means? Reject the null hypothesis since the p-value is greater than the significance level. Accept the null hypothesis since the p-value is greater than the significance level. Reject the null hypothesis since the p-value is less than the significance level. Accept the null hypothesis since the p-value is less than the significance level.

Explanation / Answer

the general rule is that

if p value is less than the level of significance then reject the null hypothesis

and if p value is greater than the level of significance then accept the null hypothesis

here level of significance is 0.05

and from the table p value=0.264

so p value>level of significance.

hence accept the null hypothesis since the p value is greater than the significance level [answer]
