a) The probability of the first serve is good for a tennis player is denoted by p. A player decides to increase p by taking a training program. After the training program completed, the player wishes to test Ho : p = 0.40 against HI : p > 0.40 . Let y be the number of first serve is good. Given that the total number of first serve, n = 20 and the critical region of the test is y 214} .

i) Determine the value of significance level, a for this test.

Find the probability of committing Type Il error if p = 0.65 .

Roger is a tennis player, he performs a serve with a 0.68 kg tennis racket. The serve took 0.4 s from the back of the swing until ball impact. The angular velocity of the racket at the start of the serve is zero, and it reaches a peak value equal to 29 rad.s-1 at the instant of ball impact. The peak linear velocity of the racket at the center of gravity is equal to 13.6 m.s-1. Calculate the moment of...

For a top player, a tennis ball may leave the racket on the serve with a speed of 55 m/s (about 120 mi/h). If the ball has a mass of 0.060 kg and is in contact with the racket for about 4 ms (4 x 10-3 s), estimate the average force on the ball. Would this force be large enough to lift a 60-kg person?
