U04A1 – Interference Using Multiple Samples

Scenario I
You are the manager of the Gander Mountain store in Frogtown, IL. Recently, a customer mentioned that they believed your prices for ammunition were lower than the prices of Gander Mountain’s primary competitor in the hunting equipment store Cabela’s. You would like to be able to include that statement in a forthcoming print advertisement, so you need statistical evidence to support the assertion.
1. Identify the null and alternative hypothesis needed to test the contention.
We are concern about the ammunition ($) difference between Gander Mountain (u1) and Cabela’s (u2).
Null: Ho: Gander Mountain (u1) < Cabela’s (u2)
Alt: Ha: Gander Mountain (u1) > Cabela’s …show more content…

Identify the null and alternative hypothesis you should form for this test. Express each in writing and also in equation form.
In this analogy, I must determine the amount of time each customer spends at the mall from days to weeks. Then figure out the means of the four variances and then determine what between and within these means. The population average for Midweek Day, Midweek, Evening, Weekend Day, and Weekend Evening, were there is significant difference means (u1, u2, u3, and u4). We want the null hypothesis test Ho: u1 = u2 = u3 = u4 and alternative hypothesis Ha: u1,u2, .. or more will be different for the others.
2. Identify the appropriate statistical test to accept or reject the null hypothesis.
In comparing of three means or more in the sample groups, we assume the statistical test would be the ANOVA – F test. Thus null hypothesis will be rejected based on the observation from F (statistic) greater than F (critical).

3. Calculate the appropriate statistical test values to accept or reject your null and alternative hypothesis.
