An industrial sewing machine uses ball bearings that are targeted to have a diameter of 0.72 inch. The lower and upperspecification limits under which the ball bearings can operate are 0.71 inch and 0.73 inch, respectively. Past experiencehas indicated that the actual diameter of the ball bearings is approximately normally distributed, with a mean of 0.724inch and a standard deviation of 0.003 inch. Complete parts (a) through (e) below.a. What is the probability that a ball bearing is between the target and the actual mean?(Round to four decimal places as needed.)b. What is the probability that a ball bearing is between the lower specification limit and the target?(Round to four decimal places as needed.)c. What is the probability that a ball bearing is above the upper specification limit?(Round to four decimal places as needed.)d. What is the probability that a ball bearing is below the lower specification limit?(Round to four decimal places as needed.)e. Of all the ball bearings, 92% of the diameters are greater than what value?inch (Round to three decimal places as needed.)

A job placement agency advertised that last year its clients, on average, had a starting salary of $39,500 . Assuming that average refers to the mean, which of the following claims must be true based on this information? Note: More than one statement could be true. If none of the statements is true, mark the appropriate box. Last year some of their clients had a starting salary of less than $35,000 . Two years ago some of their clients had a starting salary of at least $39,500 . Last year, the number of their clients who had a starting salary of more than $39,500 was equal to the number of their clients who had a starting salary of less than $39,500 . Last year at least one of their clients had a starting salary of exactly $39,500 . Last year all of their clients had a starting salary of at least $39,500 . None of the above statements are true.
