A random sample of 60 12th-grade students was asked how long it took to get to school. The sample mean was 16.9 minutes and the sample standard deviation was 11.3 minutes. a. Find a 95% confidence interval for the population mean time it takes 12th-grade students to get to school. b. Would a 90% confidence interval based on this sample data be wider or narrower than the 95% confidence interval? Explain. Check your answer by constructing a 90% confidence interval and comparing the width of the interval with the width of the 95% confidence interval you found in part (a). . . . . . a. The 95% confidence interval is from minutes to minutes. (Round to two decimal places as needed. Use ascending order.) b. Would a 90% confidence interval based on this sample be wider or narrower than the 95% confidence interval? O A. The 95% interval is wider because it has a greater confidence level, and therefore uses a larger critical value, which creates a wider interval. ith O B. The 90% interval is wider because it has a lower confidence level, and therefore uses a greater standard error, which creates a wider interval. O C. The 90% interval is wider because it has a lower confidence level, and therefore uses a smaller critical value, which creates a wider interval. O D. The 95% interval is wider because it has a greater confidence level, and therefore uses a greater standard error, which creates a wider interval. Check your answer by constructing a 90% confidence interval and comparing the width of the interval with the width of the 95% confidence interval you found in part (a). -5 The 90% confidence interval is from |minutes to minutes. AVE (Round to two decimal places as needed. Use ascending order.) This interval is the interval in part a. BED
