Answer 1

Answer #1

Correct option:

False

Explanation:
H0: Null Hypothesis: All treatment levels have the same true mean

HA: Alternative Hypothesis: All treatment levels do not have the same true mean

Since p - value is very small, the difference is significant. Reject null hypothesis.

Conclusion:

All treatment levels do not have the same true mean

Suppose that there is a very small p-value in the row labeled “treatments” in the ANOVA table for a completely randomized design. True or False: This suggests that all the treatment levels have the same true mean ) For simple linear regression, suppose that we examine a residual plot and find that the residuals are generally more-dispersed at lower levels of the explanatory variable. True or False: This suggests that one of the assumptions for simple linear regression is violated....
