What is the probability that the mean GPA for 64 randomly selected BYU-Idaho students will be less than 3.5? Round your answer to three decimal places. Use the following information to answer the next 4 questions.Tanker trucks are designed to carry huge quantities of gasoline from refineries to filling stations. A factory that manufactures the tank of the trucks claims to manufacture tanks with a capacity of 8550 gallons of gasoline. The actual capacity of the tanks is normally distributed with mean μ=8544{"version":"1.1","math":"\mu = 8544"} gallons and standard deviation σ=12{"version":"1.1","math":"\sigma = 12"} gallons.on 71 / 1 pointFind the z-score corresponding to a tank with a capacity of 8550 gallons. Round your answer to one decimal place. (Example: 0.3) Question 80 / 1 pointWhat is the probability that a randomly selected tank will have a capacity of less than 8550 gallons? Round your answer to three decimal places. (Example: 0.398)
