Post two of the six exercises from the list for Hypothesis Testing. Post both exercises in a single thread for grading.
Include the chapter number and exercise number in the title of the posting, e.g., 9.5.75 & 9.5.115.
Hypothesis Testing-Single Sample: 9.5.74, 9.5.75, 9.5.78, 9.5.79, 9.5.80, 9.5.81
Use a level of 5% unless otherwise stated. If the sample size is less than n=30, use a “t” distribution instead of “Z.”
Do not compute p-value for “t”distribution problems. Just compare the test value of “t” with the critical value corresponding to the given level. See examples in Videos-Topics In Stat 230. Click on link below for example of p-value for lower tail test.
