A statistics tutor wishes to study the effect that his tutoring has on his students. He randomly selects 4 newstudents and records their current grades in their statistics courses. After half a semester of tutoring, thestudents' grades are recorded again. The statistics tutor then uses a paired, two-sample hypothesis test todetermine if the differences between the before and after grades are statistically significant. (The tutorassumes a 5% level of significance.)Students:AВC DBefore83789387After80809686 d. Calculate the p-value from this hypothesis test.p =e. Which of the following is an appropriate conclusion?Given that p < a at a 5% level of significance, from the sample data, there is sufficient evidenceto conclude that the tutor is, in fact, effective.Given that p > a at a 5% level of significance, from the sample data, there is sufficient evidenceto conclude that the tutor is, in fact, effective.Given that p > a at a 5% level of significance, from the sample data, there is not sufficientevidence to conclude that the tutor is, in fact, effective.Given that p < a at a 5% level of significance, from the sample data, there is not sufficientevidence to conclude that the tutor is, in fact, effective.

Please give correct answer ASAP Example 5: A local college is interested in knowing if the proportion of high school students taking a fourth year of math is greater for students in suburban schools than in rural schools. To help answer this question, the college obtains a random sample of 500 senior students from suburban school districts and a random sample of 450 senior students from rural school districts across the country. The survey reveals that, of the 500 suburban students, 323 are taking a fourth year of math while only 279 of the 450 rural students are taking a fourth year of math. Is there evidence to suggest that the proportion of seniors taking a fourth year of math in suburban school districts is greater than the proportion of seniors taking a fourth year of math in rural school districts at the 5% level?
A travel agency plans to develop a new ad campaign to entice visitors to come to the Treasure Coast. As a part of the new campaign, the agency would like to advertise the warm ocean water along the Treasure Coast but would like to do so accurately.

Sample: 86,75, 83, 84, 81, 77, 78, 79, 79,81, 76, 85, 70,76, 79,81, 73, 74, 72, 83. 1) Does this sample indicate that the insurance company should change its premiums because life expectancy has increased? 2) For more accurate cost determination, the insurance companies want to estimate the life expectancy to within one year with 95% confidence. How many randomly selected records would you need to have?
