Two different rifles are tested at the shooting range. 190 shots were fired from the first rifle and the target was hit 158 times. 140 shots were fired from the second rifle, with 107 hits. Use the z-values rounded to two decimal places to obtain the answers. a. Is it reasonable to conclude that both rifles have the same accuracy? Use a = 0.05. Find the P-value for this test. b. Construct a 95% confidence interval for the difference in the two rifles accuracy.

The Athletics Department at a high school is interested in the difference in the run times between 11th and 12th grade students. Suppose the 11th grade students make up the first sample while the 12th grade students make up the second.Using a confidence level of 95%, the confidence interval found was (−1.8,2.9)(-1.8,2.9).Which of the following is the correct interpretation? We are 95% confident that the run times of the 11th grade students are, on average, faster than those of the 12th grade students. We are 95% confident that the run times of the 11th grade students are, on average, slower than those of the 12th grade students. We are 95% confident that the run times of the 11th grade students are, on average, about the same as those of the 12th grade students.
