Reconsider Dr. Sameer’s research question about how much time Cal Poly students spend on watching television, and recall that for the random sample of 100 Cal Poly students’ number of hours per day spent watching TV the mean and standard deviation turned out to be 3.01 hours and 1.97 hours, respectively.
a. In the context of this study, is the theory-based approach (one-sample t-test) valid to find a p-value to investigate whether the data provide evidence that the average number of hours per day Cal Poly students spend watching TV is different from 2.75 hours? Explain.
b. Regardless of your answer in (a), use the Theory-Based Inference applet to conduct a one-sample t-test to find and report a standardized statistic (t statistic) and a p-value for Dr. Sameer’s hypotheses.

c. State your conclusion from this study based on the p-value reported in (b), being sure to provide justification for your conclusion.
