If the user submitting the challenge would have read the book, weare always to round DOWN (page 373 in the top box, last sentence)for df calculations not up so it is still 13 df, but with a 1.82 tvalue.

T-Test of difference = 1 (vs >):

T-Value = 1.82 P-Value = 0.046

DF = 13

table value at 13DF is 1.771

since calculated value is greater than the table vaule we rejectthe null hypothesis

Also the p-value is <0.05 we reject the null hypothesis
