When women were finally allowed to become pilots of fighter jets, engineers needed to redesign the ejection seats because they had been originally designed for men only. The ejection seats were designed for men weighing between 140 lb and 211 lb. Weights of women are now normally distributed with a mean of 162 Ib and a standard deviation of - ib. Complete parts (a) through (c) below. a. If 1 woman is randomly selected, find the probability that her weight is between 140 lb and 211 lb. The probability is approximately 0.5882. (Round to four decimal places as needed.) b. If 25 different women are randomly selected, find the probability that their mean weight is between 140 lb and 211 lb. The probability is approximately (Round to four decimal places as needed.)

Assume that the readings on the thermometers are normally distributed with a mean of 0 degrees and standard deviation of 1.00degreesC. A thermometer is randomly selected and tested. Draw a sketch and find the temperature reading corresponding to Upper P 90, the 90th percentile. This is the temperature reading separating the bottom 90% from the top 10%.
