O f = mean number of hours per week all customers use the Internet 0 ,u = mean number of hours per week all customers use the Internet 0 f = 7.2 hours 0 ,u = 7.2 hours 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. Use the information from the sample to give the best estimate of the population parameter. 0 f = mean number of hours per week all customers use the Internet 0 p = mean number of hours per week all customers use the Internet 0 f = 7.2 hours 0 p = 7.2 hours 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. The standard error is about 0.458. Find a 95% condence interval for the parameter. Round the margin of error to two decimal places. 0 5.82 to 8.58 hours 0 6.28 to 8.12 hours 0 6.77 to 7.43 hours 0 7.04 to 7.66 hours
