A researcher finds a test statistic that falls in the rejection region; however, not all of the assumptions are compeltely valid. Select the appropriate statement. O We cannot conclude H1, but give our decision there is a concern of an inflated Type I error. O We cannot conclude H1, but give our decision there is a concern of an inflated Type Il error. O We can conclude H1, but give our decision there is a concern of an inflated Type I error. We can conclude H1, but give our decision there is a concern of an inflated Type Il error.

The last part of the question, the options are:   sufficient OR insufficient; support OR do not support.   Thx!

In hypothesis testing, if the test statistic falls in the critical region then we reject the null hypothesis. a. Trueb. False

Mean=3.003 SD =0.058 Num samples=100 2.80 2.90 3 3.10 Sample means A certain fast-food location claims that the average (mean) wait time in the drive-thru lane is 3 minutes. One customer thinks that the average wait time is actually longer than that, and so the customer takes a random sample of drive-thru lane wait times. The customer observes 72 transactions, and the average (mean) wait time for these 72 transactions is 3.6 minutes. In order to conduct a statistical analysis, an applet was used to see if the candidate's claim is plausible. Use the distribution of 100 simulated statistics generated by the applet (pictured above) to answer the questions. a) There are 100 little squares in the simulated distribution. What does each little square represent? O The average wait time of a sample of 72 drive thru transactions if we assume that the average wait time for all transactions is atually 3 minutes. The average wait time of a sample of 100 drive thru transactions if we assume that the…
