The weight of a 5th grader is normally distributed with a mean of 65 pounds and a variance of 86 pounds*2. Let weight, in pounds, be represented by random variable X. Question 3 P(61xx2)-0.0990. Find x2. (Remember the label.) pounds The Economic Policy Institute reports that the average entry-level wage for male college graduates is $20.24 per hour and for female college graduates is $19.72 per hour. The standard deviation for male graduates is $3.94 and for female graduates is $2.67. Assume wages are normally distributed. (See exercise 23 on page 326 of your textbook for a similar problem.) Question 4 If 54 male graduates are chosen, find the probability the sample average entry-level wage is at least $19.23.
