Question

Emma's .. che-Go, a large convenience store that makes a good deal of money from magazine sales, has three possible locations in the store for its magazine
rack: in the front of the store (to attract "impulse buying" by all customers), on the left-hand side of the store (to attract teenagers who are on that side of the
store looking at the candy and soda), and in the back of the store (to attract the adults searching through the alcohol cases). The manager at Emma's
experiments over the course of several months by rotating the magazine rack among the three locations, choosing a sample of 47 days at each location. Each
day, the manager records the amount of money brought in from the sale of magazines.
Below are the sample mean daily sales (in dollars) for each of the locations, as well as the sample variances:

Suppose that we were to perform a one-way, independent-samples ANOVA test to decide if there is a significant difference in the mean daily sales among the
three locations.
Answer the following, carrying your intermediate computations to at least three decimal places and rounding your responses to at least one decimal place.
(a) What is the value of the mean square for error (the "within
groups" mean square) that would be reported in the ANOVA
test?
(b) What is the value of the mean square for treatments (the
"between groups" mean square) that would be reported in the |
ANOVA test?

True or False
Describe a situation where you would use a test of significance on the difference between the means of two populations by stating a pair of populations composed of the same type of individuals and a quantitative variable on those populations. You may want to mention hypotheses, the sizes of samples from those populations, and the degrees of freedom of your test statistic.
Hello, May I get help on this VERY SOON please? I’m extremely confused and a clear explanation would be helpful! Thank you!
What is the null hypothesis? Why do we want to reject our null hypothesis? The first step is the find the mean of our sample and compare it to the "hypothesized" mean of our null hypothesis—why do we do that? We use the results of our first step to calculate a test-statistic. Why is this important and how does it relate to the concept of z-score, which we learned a few weeks ago? What is a p-value? What role does it play in the rejection of the null hypothesis? What does it mean to reject the null hypothesis? Does that guarantee that the null hypothesis is false?
