Question 602524
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 5.5, 4.4, 2.8, 2.5, 4.0, and 4.8.
sample mean = (sum of data)/6 = 4
sample standard deviation: 1.16
----------------------------
(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.)
Ho: u = 4
Ha: u > 4 (claim)
-------
t(4) = (4-4)/(1.6/sqrt(6)) = 0
----
p-valu = P(t > 0 when df = 5) = 0.50
Since the p-value is greater than 5%, fail to reject Ho.
Conclusion: The test results do not support the claim.
