State the appropriate hypotheses that you wish to test. (4 points) b. Use the p-value shown on your printout to state the appropriate conclusion in the words of the problem. You should choose the a to test at. (4 points) ted statesExplanation / Answer
a. The null and alternative hypothesis is
H0: All group means are equal
Ha : there are at least two group means that are statistically significantly different from each other.
b. The p-value (0.009) is less than 0.05. This shows that we reject the null hypothesis and concluded that there is a difference in means of al least one group.
c. Yes, differences can be detected. This is becuase the mean prices of one significantly differ from one another. This supports our conclusion that there is sufficient evidence to indicate that at least two mean prices differ from other.
