Read the above summary to answer these questions: 1. Find the t-score for this confidence interval.(use t-distribution) enter the positive z-score. 2. Find the standard of error for this confidence interval and round to 4 decimal places. 3. Find the margins of error round answer to 4 decimal places. Find and interpret a 99% confidence interval for the mean number of hours per week that high school seniors in Pennsylvania spend on the computer. ### 6.100 How Many Hours on a Computer?Exercise 1.24 introduces the dataset **PASeniors**, which includes many variables on a sample of high school seniors in Pennsylvania. One of the variables is **ComputerHours**, which gives the number of hours the student spent on a computer during the previous week. In the sample, 447 students answered the question, and the sample mean was 16.740 hours with a standard deviation of 17.688.

Given information Sample size (n) = 447 Sample mean x̅ = 16.740 hours Standard deviation (s) = 17.688 hours Significance level (α) = 0.01 Since, here population standard deviation is unknown therefore using t-distribution.
