The certificate in Computers has a duration which approximates a normal distribution with a mean of 266 months and a standard deviation of 16 months. What is the probability that the certificate last between 240 and 270 days? *
Solutions
Expert Solution
µ = 266
= P(-1.625 < Z < 0.25)
= P(Z < 0.25) - P(Z < -1.625)
= 0.5987 - 0.0521
= 0.5466

Which of the following is NOT a characteristic of the normal
probability distribution?
The mean, median, and mode are equal.
It is asymptotic, meaning the curve approaches, but never
touches, the x-axis.
It is symmetrical and bell-shaped.
