0.5/ points 0.5 How many hours of lecture did you physically attend over this past week? (e.g if you attended only a Tu lecture but not Th, then 1.5 hours; if you attended M and W but not F lecture then 2 hours; do not include hours watching video captured lectures from canvas for part (a).) 0 0.5 1 1.5 2 2.5 3 0 0.5 1 1.5 2 2.5 3 Answer Key: 8.b If you missed any of the 3 hours of lecture this past week, did you watch some or all of that corresponding content through the provided video captured lectures (Active Learning Platform or Lecture Recordings) on canvas this past week? Yes, I watched all the missed lectures using provided video captured lectures. Yes, I watched some, but not all missed lectures using provided video captured lectures. No, I did not watch any of the missed lectures using provided video captured lectures. Not Applicable, as I attended all lectures this past week.
0.5/0.5 point(s) Question 9 : Hypothesis Test: Decision A hypothesis test gives a p-value of 0.05. If the significance level is set at 0.05, the results are said to be: not statistically significant statistically significant inconclusive because the p-value is not smaller nor larger than the significance level
statistically significant Explanation: Results are statistically significant if the p-value is less than or EQUAL TO the significance level. Return to the top 1/ point 1 Think about the test statistic value: Consider the formula for the z test statistic. Although its exact value cannot be computed without knowing the actual sample size n, it can be determined that the resulting test statistic value will be: Go to question: Question 10 Background : An Unusual P-Value Suppose a researcher collected data to assess if a “majority” of all residents of a particular city were in favor of a newly proposed city ordinance. Her hypotheses are H : p = 0.5 versus H : p > 0.5. A large enough random sample of residents was obtained and the resulting sample proportion was 0.41. Question 10 Subquestions Think about the test statistic value: Consider the formula for the z test statistic. Although its exact value cannot be computed without knowing the actual sample size n, it can be determined that the resulting test statistic value will be: 1 2 3 4 5 6 7 8 9 10 0 a 10.a
