Question

Finally, the player wants to compare both the new club and his current club with a new technique he is thinking about using. At the same distance, with this new technique, he wants to see if the proportion of balls he can land within 5 feet is different between his old club, p1, and this new club, p2. He wants to test

H0 :p2−p1 =0 vs Ha :p2−p1 ̸=0
He hits 50 balls with the old club and 50 with the new club, and has gotten 29 successes

with the old club and 23 with the new club.
