(5 points) Problem #6 (a) On page 40 of the workbook, we found that the z-scores Zo.05 ~ 1.64485 and Zo.95 ~ -1.64485 divide the standard normal distribution so that the area in the middle is 90% with two outside tail sections of 5% each. For each of the following values for the middle area under the standard normal curve, determine the area of each tail section. Then determine the two z-scores that divide the standard normal distribution with that the area in the middle. The values for a middle area of 90% have already been filled in. Middle Area Area of each tail section Two-scores 90% 5% Z =+1.64485 92% 94% 95% 97% 99% (b) Looking at the table you created, fill-in each of the following blanks with one of the words (larger, smaller or unchanged). As the area in the middle gets larger, the tail sections get As the area in the middle get larger, the positive z-score gets As the area in the middle gets larger, the total area under the standard normal curve remains
