I need help. I cannot get this computed correctly.

Imagine the researcher is now interested in the productivity of all five (5) foreign language teachers in one school. The population has the following productivity scores (participant #, productivity score): #16, 46; #26, 38; #33, 36; #38, 48; and #40, 49. Use this population as the basis for constructing a frequency distribution histogram of sample means for n = 2.

How many unique samples of size 2 can be obtained from the population of

productivity scores of all 5 foreign language teachers? (Hint: 46, 38 is the same as 38, 46order is not important).

b. Of those possible samples of 2, how many would result in a mean score of equal to or less than 42? Calculate a mean for each of the samples of size 2. Report those means in a table.

c. Use SPSS to calculate the mean, standard deviation, and standard error for all of the productivity scores. Review Activities 2, 3, and 4 if it is unclear how to compute those values. How does the population mean relate to the sample means calculated in parts a and b?
