- If, in a (two-tail) hypothesis test, the p-value is 0.1144, what is your statistical decision if you test the null hypothesis at the 0.07 level of significance? Please choose from the answers in the pictureIf a null hypothesis is not rejected at the 0.10 level of significance, it 1 must be rejected at the 0.05 level of significance. 2 might be rejected at the 0.05 level of significance. 3 will not be rejected at the 0.05 level of significance. 4 must be rejected at the 0.01 level of significance.Are freshmen psychology majors less likely to change their major before they graduate compared to freshmen business majors? 355 of the 641 freshmen psychology majors from a recent study changed their major before they graduated and 404 of the 674 freshmen business majors changed their major before they graduated.

- If you have do not have enough evidence to reject the null hypothesis at the 5% significance level using the critical value method, you will not have enough evidence to reject at the 10% significance level. True O FalseThe body weight of a healthy 3-month-old colt should be about ? = 68 kg. (a) If you want to set up a statistical test to challenge the claim that ? = 68 kg, what would you use for the null hypothesis H0? ? > 68 kg? < 68 kg ? = 68 kg? ≠ 68 kg (b) In Nevada, there are many herds of wild horses. Suppose you want to test the claim that the average weight of a wild Nevada colt (3 months old) is less than 68 kg. What would you use for the alternate hypothesis H1? ? > 68 kg? < 68 kg ? = 68 kg? ≠ 68 kg (c) Suppose you want to test the claim that the average weight of such a wild colt is greater than 68 kg. What would you use for the alternate hypothesis? ? > 68 kg? < 68 kg ? = 68 kg? ≠ 68 kg (d) Suppose you want to test the claim that the average weight of such a wild colt is different from 68 kg. What would you use for the alternate hypothesis? ? > 68 kg? < 68 kg ? = 68 kg? ≠ 68 kg (e) For each of the tests in parts (b), (c), and (d), respectively,…Suppose a hypothesis test was performed with a level of significance of 0.05. Then if the null hypothesis is actually true, then there is a 5% chance that the researcher will end up rejecting the null hypothesis in error. True False
- Based on certain data, a null hypothesis is rejected atthe 0.05 level of significance. Would it also be rejectedat the(a) 0.01 level of significance;(b) 0.10 level of significance?Records from a toy manufacturing company showed that the mean time that the top-selling toy captured children’s attention was 40 minutes. A competing company strongly suspects that the mean time will be less than 40 minutes for the new generation of children and wishes to carry out a hypothesis test. State the null hypothesis H0 and the alternative hypothesis H1 that we would use for this test.When a result is not extreme enough to reject the null hypothesis, explain why it is wrong to conclude that your result supports the null hypothesis.
