Assume, historically, the distribution of the home-run (HR) and wins for each team'sseason games follow a normal distribution with means 179 and 75 respectively and withvariances of 1000 and 12 respectively. ESPN hires you to investigate whether the averageteam's HR in 2018 season was higher at 0.10 significance level.a. State the null and the alternate hypotheses?b. What is your final decision and justify your answer? That is, perform a hypothesistest.c. Using a 0.05 significance level, conduct a hypothesis test to determine whether themean win was more than 75?

Which statement best represents the logic of a one way analysis of variance which also called ANOVA which is also called the F test? A. Under the null, The population means are equal to each other, so any difference in sample means will register as significant difference B. Under the null, at least one mean is different from the others, so if this condition is met with the data, it will register as a significant difference C. Under the null, The means are assumed to be equal; as a result the between group variance will equal the within group variance ; if the calculated SSbetween is sufficiently larger than SSbetween this would suggest the between group variation is larger than within group variation and indicate there is a significant difference amount the means D. Under the null, the means are assumed to be equal, as a result, the within group variance will be larger than the between group variance and this will be revealed by a significant F, which would indicate that the…
