A report by the NCAA states that 57.6% of football injuries occur during practice. A conference official claims that this figure is too high for his conference. He randomly selected 38 injuries and found that 22 were occurred during practice. Use a level of significance of α = 0.10 to test the claim.       Step 1 State the null hypothesis H0 and alternative hypothesis Ha as mathematical sentences H0     Ha     Step 2 Identify which hypothesis represents the claim       Step 3 Determine whether the hypothesis test is right-tailed, left-tailed, or two-tailed       Step 4 Find the test statistics z                     Step 5 Find the P-value           Step 6 Compare P and α / Interpret the results

2-Proportion Test

In a 2-proportion test, two separate proportions are measured at the same time, and their similarity is evaluated. It is also known as a 2-proportion z-test, and a comparison of two different proportions is done in this method.
