Suppose that the commuting time on a particular train is uniformly distributed between 38 and 58 minutes.

a.What is the probability that the commuting time will be less than 44

minutes?

b.What is the probability that the commuting time will be between 41 and 55 minutes?

c.What is the probability that the commuting time will be greater than

49 minutes?

d.What are the mean and standard deviation of the commuting time?

a. The probability that the commuting time will be less than 44 minutes is

(Type an integer or a decimal.)

b. The probability that the commuting time will be between 41 and 55 minutes is

(Type an integer or a decimal.)

c. The probability that the commuting time will be greater than 49 is

(Type an integer or a decimal.)

d. The mean of the given uniform distribution is =nothing.

(Type an integer or a decimal.)The standard deviation of the given uniform distribution is

=

(Round to four decimal places as needed.)
