3) Find P(x > 61) the probability x is greater than 61. (5 points) 4) Find P(68 < x < 91) the probability that x is greater than 68 and less than or equal to 91. (5 points) 5) Suppose x is normally distributed with a mean of 50 a standard deviation of o = 7. Find the 90th percentile (the value of x so that the area to the left is 0.9.) (5 points)
