Question

Use the data set provided ibelow
1. Complete the full hypothesis testing procedure to determine if students at TCC watch less television than Americans in general. Use the fact that Americans watch 5.5 hours of television per day with a standard deviation of 1 hour per day. Include the following in your report:
a) Hypotheses using correct notation (2 points)
b) type of test (left, right, two-tailed) (1 point), distribution used (normal or t) (1 point), reasons why (2 points)
c) level of significance, choose one based on how serious the study is (2 points)
d) Sample statistics (sample size and sample mean or sample proportion) (2 points)
e) P-Value (2 point) (Round answer to four decimal places)
f) Interpretation of P-value (Use Definition of P-Value but be specific to this context) (1 point)
g) Drawing or graph of P-value. (2 points)
h) Decision (2 point)
i) Conclusion in complete sentences. (3 points)

datt ( number of hours of TV watched per day

4 5 2 2 0.5 2.5 1 2 3.5 6 1.5 2 1 6.5 7 3 3 3 1 1.5 4 6.5 3 2 4 1 2 2 2.5

Answer 1

Let denote the mean number of hours of TV watched per day by students at TCC

Assuming level of significance = 0.05

This test is a left tailed test as the alternative hypothesis contains " <" sign.
