Given the scenario below, what is the obtained statistic (obtained value)? Americans typically take off 5 sick days each year, with a standard deviation of 2 days. A researcher would like to know whether psychiatrists take off less sick days than the average American. The researcher obtains a sample of 16 psychiatrists who, on average, take 3 days of sick leave a year. Test this researcher s hypothesis using an alpha level of .01.

Question
QUESTION 16 Given the scenario below, what is the obtained statistic (obtained value)? Americans typically take off 5 sick days each year, with a standard deviation of 2 days. A researcher would like to know whether psychiatrists take off less sick days than the average American. The researcher obtains a sample of 16 psychiatrists who, on average, take 3 days of sick leave a year. Test this researcher s hypothesis using an alpha level of .01. QUESTION 17 "For an independent t-test, if you have the mean of group 1, mean of group 2, SS group 1, SS group 2; and the alpha level, what else do you need to compute t-obtained? " Power effect size of the Independent Variable O Sample Size Beta QUESTION 18 The critical values for a 2-tailed sign test for 13-coin flips (alpha of .05) is: O and 13 2 and 11 1 and 12 3 and 10
