Similar devices have been criticized for being too easy to master, but the makers of Photon say that their device is built to give most users room to improve. The makers say that even among professional athletes, the proportion, p, who can score the top ranking of "light speed" is less than 24%. A random sample of 115 professional athletes is chosen, and 16 score a ranking of "light speed" while using the device. Complete the parts below to perform a hypothesis test to see if there is enough evidence, at the 0.05 level of significance, to support the claim that the proportion of all professional athletes who can score a ranking of "light speed" is less than 24%. (a) State the null hypothesis Ho and the alternative hypothesis H₁ that you would use for the test. 13 EPIC VE VE • The value of the test statistic is given by z = X (c) Perform a Z-test. Here is some information to help you with your Z-test. • 70.05 is the value that cuts off an area of 0.05 in the right tail of the distribution. р-р p(1-P) n p USO (b) For your hypothesis test, you will use a Z-test. Find the values of np and n (1-p) to confirm that a Z-test can be used. (One standard is that np > 10 and n (1-p) ≥ 10 under the assumption that the null hypothesis is true.)
