Suppose Abby tracks her travel time to work for 60 days and determines that her mean travel time, in minutes, is 35.6. Assume O Feedback the travel times are normally distributed with a standard deviation of 10.3 min. Determine the travel time x such that 29.46% of The proportion of travel times that are the 60 days have a travel time that is at least x. at least x is represented symbolically as You may find this standard normal distribution table or this list of software manuals useful. Give your answer rounded to two P(X > 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.
