Reconsider Dr. Sameer’s research question about how much time Cal Poly students spend on watching television. Suppose that Dr. Sameer surveys a random sample of 100 Cal Poly students, and for this sample the mean number of hours per day spent watching TV turns out to be 3.01 hours.

a. Is the number 3.01 a parameter or a statistic?

b. Assign an appropriate symbol to the number 3.01.

c. Describe how you can conduct a simulation-based test of significance 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. Be sure to provide details on how one would find a p-value.

d. For the following table, complete the column on the right to draw parallels between the simulation and the real study:
