PLEASE HELP ME FIND THE CORRECT P-VALUES

A restaurant chain is interested in determining if mean weekly revenue differs among three of its restaurants in a particular city. The table below shows the revenue data for a sample of weeks for each of these three locations. Complete parts a through c below Click the icon to view the data a. Test to determine if blocking the week on which testing was done was necessary. Use a significance level of 0.05 Determine the null and alternative hypotheses for this test. Choose the correct answer below. HA: Not all means are equal HA: All means are unequal HA: Not all means are equal HA: At least two populations have different means H0: At least two populations have different means ° C. 0 E. H0: Not all means are equal What is the p-value for this test? p-value = 1701 (Round to three decimal places as needed.) What is the conclusion for this test? The p-value is greater than the significance level, so rejec the null hypothesis. There is sufficient evidence to conclude that blocking was effective b. Based on the data gathered by the restaurant chain, can it be concluded that there is a difference in the average revenue among the three restaurants? Determine the null and alternative hypotheses for this test. Choose the correct answer below OA. H HA: All means are unequal HA: Not all means are equal D. Ho: All means are unequal HA: All means are unequal (blocking is effective) E. Ho: At least two populations have different means HA: At least two populations have different means What is the p-value for this test? p-value 015 (Round to three decimal places as needed.) What is the conclusion for this test? The p-value is less than the significance level, so reject the null hypothesis. There is sufficient evidence to conclude that there are differences in the average weekly revenue across the three restaurants

Explanation / Answer

Sol:

its one way -ANOVA

Ho:All the restaurant group means areequal

H1:Atleast one of the means are different

OPTION F FROM GIVEN CHOICES.

p=0.170

p>alpha

fail to reject null hypothesis.

there is no sufficient evidence to conclude that blocing was effective
