A programmer plans to develop a new software system. In planning for the operating system that he will use, he needs to estimate the percentage of computers that use a new operating system. How many computers must be surveyed in order to be 99% confident that his estimate is in error by no more than two percentage points? Complete parts (a through (c) below. a) Assume that nothing is known about the percentage of computers with new operating systeme (Round...

In order to estimate the mean amount of time computer users spend on the internet each​ month, how many computer users must be surveyed in order to be 90​% confident that your sample mean is within 14 minutes of the population​ mean? Assume that the standard deviation of the population of monthly time spent on the internet is 198 min. The minimum sample size required is_______computer users. Many states are carefully considering steps that would help them collect sales taxes...
Find the sample size, n, needed to estimate the percentage of adults who have consulted fortune tellers. Use a 0.04 margin of error, use a confidence level of 98% and use results from a prior poll suggesting that 11% of adults have consulted fortune tellers. A student wants to estimate the mean score of all college students for a particular exam. First use the range rule of thumb to make a rough estimate of the standard deviation of those scores....
