A schoolteacher is concerned that her students watch more TV than the average American child. She reads that according to the American Academy of Pediatrics (AAP), the average American child watches 4 hours of TV per day
(μ = 4.0 hours).
She records the number of hours of TV each of her six students watch per day. The times (in hours) are 2.7, 5.5, 4.8, 2.7, 4.4, and 3.9.
(a) Test the hypothesis that her students watch more TV than the
average American child using a 0.05 level of significance and a
one-independent sample t-test. State the value of the test
statistic. (Round your answer to three decimal places.)
t =
(b) Compute effect size using estimated Cohen's d. (Round
your answer to two decimal places.)
d =
