QUESTION 3 A research study found that adolescents watch on average, 8.7 hours of television each data. We think that the true population average is lower than that. We collected our own sample \((N= 250, M=5.7, SD=1.87)\). Set alpha level to 0.05. What is the research hypothesis?

Question 2 The sponsors of TV shows targeted at the market of 5- to 8-year olds want to test the hypothesis that children watch television for 20 hours per week. TV hours are only known to be normally distributed. A market research firm collected a random sample of 25 children in this age group. The hypothesis testing results were derived in Excel. Unfortunately, Excel got corrupted and the firm's analyst accidentally deleted the data. The analyst retrieved an incomplete results table (displayed below) and could only recall that the estimated sample mean is higher than 20. a) Suppose you are the analyst, use your knowledge from MS 251 to complete the table. Sample Size: 25 Sample Mean Population Std. Dev.: 6 Hypothesized Value: 20 Standard Error Test Statistic p-value (Two Tail): 0.50 b) Provide the null and alternative hypotheses, the decision about whether to reject the null, and the contextual conclusion. Assume a .10 level of significance.
