An Internet provider contacts a random sample of 300 customers and asks how many hours per week the customers use the Internet. It found the average amount of time spent on the Internet per week to be about 7.2 hours. Percentiles of the bootstrap distribution are provided. Use the percentiles to report a 95% confidence interval for the parameter. 1% 2.5% 5% 10% 25% 50% 75% 90% 95% 97.5% 99% 6.174 6.322 6.438 6.593 6.866 7.17 7.481 7.78 7.947 8.082 8.304 6.174 hours to 8.304 hours 6.322 hours to 8.082 hours 6.438 hours to 7.947 hours 6.593 hours to 7.78 hours

A random sample of 300 customers was contacted by an Internet provider to determine the average amount of hours per week that customers use the Internet. The sample participants reported an average of 7.2 hours per week. The standard error for the time spent was found to be 0.458. (a) Find the margin of error, using the given standard error, for a 99% confidence interval for the average amount of time all customers use the Internet. Use the result from part (a) to find the 99% confidence interval for the parameter. Round to two decimal places and show work.

An Internet server conducted a survey of 500 of its customers and found that the average amount of time spent online was 17.5 hours per week with a standard deviation of 3.4 hours. a. Construct a 99% confidence interval for the average online time for all users of the particular Internet server. (using One-Sample Z menu) b. Construct an 88% confidence interval for the average online time for all users of the particular Internet server. (using One-Sample Z menu)

As part of his class project, a Statistics student took a random sample of 50 college students and recorded how many hours a week they spent on the Internet. The sample reveals an average of 6.9 hrs. Calculate the 90% confidence interval for average Internet usage among college students. Assume that the standard deviation of Internet usage for college students is 4.5 hrs/week. Answer 1&2 1) A) E = 1.58 B) E = 2.02 C) E = 1.05 D) E = 2.58 2) A) 5.85 < μ < 7.95 B) 5.32 < μ < 8.48 C) 4.32 < μ < 9.48 D) 4.88 < μ < 8.92
