BADM 701 Fall 17 mework: Homework #7 (Chapter 8) e: 0 of 1 pt tructor-created question Example 8.2 on p. 424, if the problem were changed so population 1 referred to the retail sales prices in Japan, and population 2 referred to the retail sales prices i 1 of 5 (0 complete) Hw Score: 0%, 0 of 17 Question Help e US, then which of the following statesments are true? (Hint the question asked remains the same, whether the mean retail sales price in Japan is higher than the ean retail sales price in the US, this question simply asking howlwhether changing the order in which the data are collected and referred to changes the set up of the problem) A. The alternative hypothesis would indicate a hypothesis that the difference in mean retal sales prices is positve O B. The rejection region would be located in the upper-tail of the distribution. than 1.645 0 D. The test statistic would be 1.62. 0 E. The conclusion would be to Fail to Reject Ho OF. A, B, C, and D are true. 0 G, A, B, and C are true. OH, Only A and B are true OL A, B, C, D, and E are all trueExplanation / Answer
From the given data we can say that the option for
A,B,C are true.
Because in alternate hypothesis the sign changes, so difference will be positive.
Since it is right tailed test, rejection will be a right tailed.
And critical value is 1.645. (Positive)
Test statistic sign will change. Since the test statistic is not mentioned in the above question I cannot comment in it. But if test statistic for earlier question, lets say is a, then it will be -a in this case.
Conclusion will be if test statistic is greater than 1.645, Reject Ho
Otherwise Do not reject Ho
