Find the following probabilities. (Round your answers to three decimal places; add trailing zeros as needed. The probability that a randomly selected adult has an IQ greater than 122.6 is type your answer. . The probability that a randomly selected adult has an IQ lower than 92.0 is |type your answer.. The probability that a randomly selected adult has an IQ between 80.0 and 110.0 is |type your answer.. 2 1 point Assume that military aircraft use ejection seats designed for men weighing between 133.8 lb and 208.0 lb. If women's weights are normally distributed with a mean of 172.6 lb and a standard deviation of 42.4 lb, what percentage of women have weights between the ejection seat's weight limits (that is, 133.8 to 208.0 lb)? (Enter your answer as a percent rounded to one decimal place (do not add a "%"); add a trailing zeros as needed.)

Assume that adult men have hip breadths that are 5 normally distributed with a mean of 14.4 inches and a standard deviation of 1.1 inches. Find the 95th percentile of the hip breadth of adult men.

Assume that as a result of the test, 3 percent of all thermometers produced will be rejected because they display temperature readings that are too high and a further 3 percent will be rejected because they display readings that are too low; the remaining 94 percent will be accepted. Find the two cut-off readings that separate the accepted thermometers from those that are rejected.
