The average number of days between deliveries to VQT Corp. is 30 days. The standard deviation is 3 days. Assume a Normal Distribution. What are the chances that the number of days will be less than 27 days?
Homework Answers
Solution :
Given that ,
mean = 
= 30
standard deviation = 
= 3
P(x < 27) = P((x -
) /
< (27 - 30) / 3)
= P(z < -1) Using standard normal table,
= 0.1587
Chances = 0.1587 = 15.87%
