This Uuestion: 1 l 4 of 15 to com are given to Find the inde pro d w racam man in the given angeb would be considered on e echology The p one and down to find the probably Fora g e of 37 find the probably a sample meaningless than 12.752 or greater than 12.755 when 12.752 and 22 For the given sample, the probability of a sample mean being an 1272 or greater than 12,755 Round to four de places as needed) Would the g amle man be considered OA The sample mean would be considered unusual because there is a probably than 00s of the sample meaning within this range OB. The sample mean would be considered us because there is a probability greater than 0.05 of the sample mean being within this range OC. The sample mean would not be considered because there is a prog ram of th e engi ne OD. The sample mean would not be considered unusual because there is a probatiss than 0.05 of the man being within this range

Answer 1

n = 37

0 = 2.2 u = 12752 P(X < 12752 or X > 12755) = P(X < 12752) + P(X > 12755) = P(X < 12752) + (1 - P(X < 12755)) - 12752 - 12752 - + 1-P- - 12755 - 12752 =pl =p(z < 0.00) + (1 - p(z < 8.29)) From z score table = 0.50 + (1 - 1) = 0.50

D. The sample mean would not be considered unusual because there is a probability less than 0.05 of the sample mean being within this range.
