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 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
