A transportation app developer knows that the commute times for a specific route follow an approximately normal distribution with a mean of 30 minutes and a standard deviation of 6 minutes. Using the norm.dist() function in excel, the developer has calculated the following probabilities for specific commute times. Probability Calculations P (Commute < 16.04) = 0.01 P (Commute < 20) = 0.048 P (Commute < 20.13) = 0.05 P (Commute < 25) = 0.202 P (Commute < 35) = 0.798 P (Commute < 39.87) = 0.95 P (Commute < 40) = 0.952 P (Commute < 43.96) = 0.99 9. What is the probability that a commute is between 25 and 40 minutes? 10. Name the two values (don't round), equidistant from the mean of 30 minutes, such that 90% of all commute times are between these values
