QUESTION 10 In a survey that asked whether the use of "Expert Answers" provided on Chegg should be considered cheating in an exam in which students were told not to discuss the exam with anyone else, 53 of 79 respondents said that it should be considered cheating. Consider the 79 respondents as a random sample and suppose you wish to determine whether over 60% of all students would consider the situation cheating. Let a = 0.10. Which of the options below is the proper way to express the null and alternative hypotheses? O A. Ho: p = 0.60 vs. H₁: p > 0.67 O B. Ho: p = 0.67 vs. H₁: p > 0.67 O C. Ho: p=0.60 vs. H₁: p > 0.60 O D. Ho: p = 0.67 vs. H₁: p > 0.60
QUESTION 1 One of the differences between the use of a one-sample t-test and z-test is: the population standard deviation the value of N the population mean whether the data come from the same people QUESTION 2 • Given X, = 25, N, = 5; X2 = 19, N2 = 5, sz, -i, = 2.5 a=0.05, 2 tail. Our conclusion would be: since df = 9, reject the null. since df=8, reject the null since df = 10, retain the null since df =8, retain the null QUESTION 3 Setting the alpha level at 0.001 instead of the usual 0.05 increases the likelihood of O Type II Error Having a small n Rejecting the Null Hypothesis. O Type I Error

QUESTION 7 Here is your data: 17, 16, 21, 18, 13, 15, 12 Which of the following statement is not true? O A. M is 16 O B. QU is 17.5 OC. We can not calculate QU and QL when the sample size is an odd number. O D. QL is 14 QUESTION 8 Continue on Q7. Which of the following statement is not true? A. Inner Fence is between 8.75 and 22.75 B. Outer Fence is between 3.5 and 28 C. According to the box plot we constructed, 21 will be an extreme outlier. O D. IQR=3.5
