(a) Draw a normal curve and write the maximum and minimum values
of z-scores with probabilities associated with these values. Also
find the area below the z equals -1.12 and above the z equals 1.12.
What is the probability of resulting values of z? (b) Saleem leaves
his house at 7.15 a.m. for his office. The time taken to reach the
office is normally distributed with mean of 50 minutes and standard
deviation of 12 minutes. What is the probability that Saleem will
