5.7 If n=5 and pie=.40 what is the probability that a. X = 4? b. X≤ 3? c. X less than 2? d. X more than 1?
6.5 Given a normal distribution with µ=100 and sigma=10 what is the probability that a. X is greater than
75? b. X is less than 70? c. X is less than 80 or X is greater than 110? d. 80% of the values are between
what two X values (symmetrically distributed around the mean)?
80% of the values are in between 87.184 and 112.816.
6.1 Given a standardized normal distribution (with a mean of 0 and a standard deviation of 1, what is the
probability that a. Z is less than 1.57? b. Z is greater than 1.84? c. Z is between 1.57 and 1.84? d. Z is less
than 1.57 or greater than 1.84?
