Suppose Abby tracks her travel time to work for 60 days and determines that her mean travel time, in minutes, is 35.6. Assume x). decimal places. P(X > x) = 0.2946 In order to find x, first find the value z such that 29.46% of the total area under 36.32 min the standard normal density curve is to the right of z. You can find z using this Incorrect standard normal distribution table or this list of software manuals. The z-score formula, where u is the mean and o is the standard deviation, can be used to convert z into travel times. %3D Be sure to round your answer correctly to two decimal places.
Tech Worx magazine reported that91%of software engineers rate the company they work for as "a good place to work."

Systolic blood pressure readings are normally distributed with a mean of 121 and standard deviation of 15. If a person from the population was selected at random, find the probability that their blood pressure is in the acceptable range (between 114 and 140) for an athletic activity. A. Label and shade the normal distribution curve to model this problem.
