Question
11. In order to estimate the mean amount of time computer users spend on the internet 10 each month, how many computer users must be surveyed in order to be 95% confident that your sample mean is within 11 minutes of the population mean? Assume that the standard deviation of the population of monthly time spent on the internet is 201 min. The minimum sample size required is computer users. What is a major obstacle to getting a good estimate of the population mean? O A. There may not be 1,283 computer users to survey. O B. It is difficult to precisely measure the amount of time spent on the internet, invalidating some data values. O C. The data does not provide information on what the computer users did while on the internet. O D. There are no obstacles to getting a good estimate of the population mean.
