A school's computer center instituted a sign-in system that allows the center to monitor the number of users on a particular day. The following data are the number of users of the lab during a 29 day period. 30 32 29 50 25 25 32 41 49 44 37 12 13 44 31 45 55 52 16 26 39 40 46 58 38 9 15 39 46 Suppose the center will decide to staff the lab with an assistant if the true average number of daily users is greater than 30, but clear evidence of this is needed to justify the expense. Assume u = 30 and calculate the value for y and s from the sample of data. Should an assistant be hired? Hint: If the true mean is 30 and the value for Y is truly more than 30, then the probability of this difference will be unusual and you can justify hiring! Also, note that you are using s in this problem and not o... ;)
