A random sample of High School students found that 256 of the students had TVs in their rooms and that the remaining 769 did not have TVs in their room. Construct and interpret a 90% confidence interval for the proportion of High School students who have TVs in their room. 1. The information tells us that the survey is a random sample. Show that this situation satisfies the following conditions: a. Show that this situation satisfies the 10% condition. (1 points) b. Show that this situation satisfies the large count condition. (1 points) 2. The general formula used to create a confidence interval is: Statistic † (critical value) (standard deviation of statistic) a. What is the statistic (or point estimate) in this example? (1 points) b. What is the critical value (rounded to 4 decimal places) to determine the confidence interval? (1 points) c. What is the standard deviation of the statistic? (2 points) 3. Calculate a 90% confidence interval for the proportion of High School students who have TVs in their room. (2 points)
