1. Find the area under the Standard Normal Distribution for each: A. Between 0 and 1.50 C. Between 1.56 and 1.96 B. To the right of z = 1.75 D. To the left of z = -2.12 2. Using the Standard Normal Distribution, find the probability of: A. P(O<z<2.16) C. Plz>1.77) B. P(-1.63<z<2.17)_ D. P(z<-2.37). 3. The average electric bill in a residential area is $72 for the month of April. The standard Deviation is $6. If the amounts are normally distributed, find the probability that the mean of the bills of 15 residents will be less than $75. Fill-in: .SD = Now find the Prob. u= n = .X = 4. The average height of a certain age group is 53". The Standard Deviation is 4". If the variable is normally distributed, find the probability that a selected individuals height will be: a.greater than 59". b. less than 45 c. between 50 & 55 Fill-in: U= u= U= S.D.= S.D. S.D. X= X = X =
