Question 16 Jason is a baseball player who has batted both left-handed and right-handed during his career. Among 3,281 left-handed at- bats, he recorded a hit on 810 of them, and he recorded a hit on 670 of 2,412 right-handed at-bats. Perform a two- proportion hypothesis test to determine whether there is a difference in Jason's true batting averages (hits divided byat- bats) between batting left and right-handed. Assume that the conditions for inference are satisfied Usea0.05. Let the eft-handed data correspond to the samole 1 and the right-handed data correspond to the sample 2. For this test Ho PI Pz:Ha PI pz, which is a two-tailed test. Screen Shot 2019-04-21 at 6.22.01 PM Question 13 Use a TI-83, TI-83 Plus, or TI-84 calculator to test if the proportions are different. Identify the test statistic, z, and p-value from the calculator output. Round your test statistic to two decimal places and your p-value to three decimal places A district manager of a grocery store wanted to determine if the totai revenue for the stores in a region had dropped since last year. The manager coWected data from 10 stores in the region. Instead of using the standard deviation from the survey the manager decided to use the financial data for the last year to assume that the population standard deviation of revenue is $28.1 thousand. Last year, the mean regional revenue was $61.4 thousand. Provide your answer below the manager conducts a one-mean hypothesis at the 5% significance level, to test if the average revenue decreased from the previous year of S61.4 thousand test statistic-p-value For this test: H() : μ-$61.4: Ha : μ < S61.4, which is , left-tailed test. B FEEDBACK Income (in thousands) of stores in the region is given below Use a TI-83, TI-83 Plus, or TI-84 calculator to test whether the mean is less than $61.4 thousand. Identify the test statistic, z and p-value from the calculator output, rounding to two decimal places. 20.2 72737.5 96.645431 60.5 20.2 49.0 712 Provide your answer below test statisticp-value Question 16 Jason is a baseball player who has batted both left-handed and right-handed during his career.
