Suppose a random sample of size 36 is drawn from a population with a mean of 272. If 87% of the time the sample mean is less than 275, what is the population standard deviation? Appendix A Statistical Tables

(Round your answer to 2 decimal places, e. g. 15.25.)
SD=

it has the same slope and a different y-intercept

hope this : )

median is the value separating the higher half of a data sample, a population or probablity distribution from the lower half.

step-by-step explanation:

say you have 3,8,7,3,1,9,8 order them from lowest to highest

if orderd it would be 1,3,3,7,8,8,9 now you take away from the lowest and the highest until you end up in the middle.

so you would remove the 1 and 9 leaving you with 5 digits remaining

when you've reached the middle that would be your answer so in this case the answer is 7

if there were two numbers left say 7 and 5 you'd and them together so 12 then divide by 2 witch would equal 6 so the answer would be 6

good luck on that project hoped i you at all

answer: about 22.67
