She reads that according to the American Academy of Pediatrics (AAP), the average American child watches 2.5 hours of TV per day.

Test the hypothesis that her students watch more TV than the average American child using a .05 level of significance and a one-tailed test. Please answer the questions based on the SPSS output shown below. Hint: For p value of one-tail, divide �Sig (2-tailed)� by 2.
one sample statistics-
tv.hour..n=20..mean=2.8300..std deviation..1.35999...std error mean?
one sample test
tv hour t=?..df=?..sig(2tailed)=.291..mean difference=?
95% confidence interval of the difference
lower...-3065.......upper.....9665

1) There are four missing values (?) in the SPSS output. Please fill in the values (see p. 16 of CH 9 notes).
a) �Std. Error Mean� =
b) �Test value� =
c) �Mean Difference� =
d) �df� =
