8.15) I looked up 1.5 and got the probability .4332 ans=.4332 8.21) I looked up 1.4 and .6 on the z value sheet and added .4192 to .2257 ans= .6449 8.22) I took -1.44 and changed it to 1.44 and looked at the z values from 0 and got the probability. ans= .0749 8.23) I took the number 2.03 and looked up the z value on the sheet and took the number from the second row. ans= .0212 8.27) I took .91 and .33 and looked up there values and subtracted them from each to get .1893 ans= .1893 8.32) I looked up the number .045 on the sheet and found that the answer was between 1.69 and 1.70 so I took the average and got 1.695 ans= 1.695 8.34) I took 145 and subtracted it by the mean then divided that number by the S.D. and got 2.25. Then I looked up the z value and found the answer. ans= .0122 8.36) I took 800 and 1100 and subtracted them by the mean two different times and then divided them by the S.D and got -.8 and .4. Once I found those numbers, I looked up the probabilities and added them together to get the answer. ans= .4435
