Unformatted text preview: by the square root of 4 and got 1.15 and I looked up the probability and got .3739 9.18 a. what I did for this question was take 5260/6 and got 1.33 and I looked it up the probability and got .4082 b. for this one I set it up the same way as a. except divided the S.D. by the square root of 6 rather than just 6 and got 3.27 and I looked up the probability and got about .4994 9.21 a. What I did was 76/1.5 which gave me Z>.67 and the probability is .2514 b. For this I did the same thing as a. but divided 1.5 by the square root of 5 and got Z>1.49 and the probability is .0681 9.26 What I did was 300288/78 but 78 is divided by the square root of 60 I to got z>1.19 which turns out to be .1170...
