In your Excel spreadsheet, delete the values from the columns containing the number of babies with those names (that is, clear the third and fifth columns). Then, have Excel compute the number of letters in each name: In the first cell of the third column (i.e., cell C1) type "=len(B1)". Copy that into all 50 rows of column C, and do the same thing for the fifth column. The third and fifth columns should now contain the number of letters in the corresponding names.

Now have Excel do a t-test on the lengths of the names. (Use Tools --> Data Analysis --> ...) Place the output of the test in the worksheet beginning at the first row of the seventh column (i.e., cell H1).

Print out one page that includes the top part of the data and the results of the t-test. What do you conclude? Do boys and girls have different length names, or can the null hypothesis of equal length names not be rejected? Write your answer underneath the output of the t-test.
