Where Is the Best Seat on the Plane? A survey of 1000 air travelers found that 60% prefer a window seat. The sample size is large enough to use the normal distribution, and a bootstrap distribution shows that the standard error is SE = 0.015. Use a normal distribution to find and interpret a 99% confidence interval for the proportion of air travelers who prefer a window seat. (4 pts total) 99% confidence interval: Interpretation of the 99% confidence interval: 3. This question may have more than one correct answers. Choose all that applies! A researcher conducted a study on whether playing video games would lower students' GPA. Results indicate that students who play video games have lower average GPAs compared to those who do not play video games. The p-value for this test is 0.012. Using at = 0.05, what would you conclude? ( ) (choose all applies; 3 pts total) A. If the null hypothesis is true, the probability of seeing a difference in mean GPA as the one in the sample is 0.012. B. The probability of see a difference in mean GPA as extreme as the one in the sample is 0.012. C. Students who play video games have significant lower GPAs. n 1319175an Uirlnn (Int-nae Pnncne let-11:11:11": tn Hang a lnnun- EDA nn aunt-urn
