Adrian hopes that his new training methods have improved his batting average. Before starting his new regimen, he was batting 0.250 in a random sample of 96 at bats. For a random sample of 56 at bats since changing his training techniques, his batting average is 0.375. Determine if there is sufficient evidence to say that his batting average has improved at the 0.02 level of significance. Let the results before starting the new regimen be Population 1 and let the results after the training be Population 2. Step 1 of 3: State the null and alternative hypotheses for the test. Fill in the blank below. Ho: P₁ = P2 Ha Pi P2

Adrian hopes that his new training methods have improved his batting average. Before starting his new regimen, he was batting 0.250 in a random
sample of 96 at bats. For a random sample of 56 at bats since changing his training techniques, his batting average is 0.375. Determine if there is
sufficient evidence to say that his batting average has improved at the 0.02 level of significance. Let the results before starting the new regimen be
Population 1 and let the results after the training be Population 2.

We reject the null hypothesis and conclude that there is insufficient evidence at a 0.02 level of significance to say that Adrian's batting average has
improved since he changed his training methods.
We fail to reject the null hypothesis and conclude that there is insufficient evidence at a 0.02 level of significance to say that Adrian's batting
average has improved since he changed his training methods.
