Los Angeles workers have an average commute of 28 minutes.
Suppose the LA commute time is normally distributed with a standard
deviation of 14 minutes. Let X represent the commute time for a
randomly selected LA worker. Round all answers to 4 decimal places
where possible. a. What is the distribution of X? X ~ N( , ) b.
Find the probability that a randomly selected LA worker has a
commute that is longer than 34 minutes. c. Find the 85th percentile
for the commute time of LA workers. minutes
