Ответ:
a. 0.30
b. 0.60
c. 0.20
d. Mean = 45, Standard Deviation = 2.8867
Step-by-step explanation:
a = 40, b = 50
a. What is the probability that the commuting time will be less than 43 minutes? Bold
P(X<43) = (43-40)/(50-40) = 0.30
b. What is the probability that the commuting time will be between 42 and 48 minutes? Bold
P(42<X<48) = (48-42)/(50-40) = 0.60
c. What is the probability that the commuting time will be greater than 48 minutes? Bold
P(X>48) = (50-48)/(50-40) = 0.20
d. What are the mean and standard deviation of the commutingtime?
1) Mean = (b+a)/2 = (40+50)/2= 45
2)SD =
