- part e onlyRecall Milgram’s infamous obedience studies. Milgram had participants give a series of increasingly painful electric shocks to another participant (actually a confederate). Milgram he found that 65% of the real participants obeyed through the end of the study, giving what they thought was 350 volts to the confederate, which was considered “lethal”. Given the infamous study and the negative attention it received, current researchers doubt that current (and more knowledgeable) participants would obey as much as the naïve participants that Milgram used in the original study. Are the researchers correct? Which is the research hypothesis? Ha: Obedience = 65% Ha: Obedience < 65%Over at NAIA, you are observing the average length of flight delays (excluding flights that leave on time). Your notes for ten randomly chosen days are here: Day Ave. delay (hrs:min) 1 2:00 2 1:48 3 0:19 4 0:25 5 2:18 6 0:43 7 0:13 8 0:17 9 0:34 10 3:12 If the airport claims that the delays will be no more than an hour on average, check his claim by doing the following: (a) Write the null hypothesis. (b) Write the alternative hypothesis. (c) Formulate and calculate the test-statistic. Is it a one-tail or two-tailed test? Did the airport told you the truth at 95% confidence level? (d) Determine the confidence interval
