The researcher conducted a hypothesis test and found the 95% confidence interval to examine whether there is a difference in high school students completion rate in percent with respect to the size of the teachers' salary (low or medium). The hypothesis test result showed p-value of 0.59 and the CI was [-2.45, 4.45]. In the space provided below, a) Explain whether the hypothesis test result and the confidence interval are in agreement. b) Explain whether and why Type 1 error...

write a confidence interval or hypothesis test problem using this option. gather data and post your problem(without a solution) Think of a problem that deals with a comparison of two population means. Propose either a confidence interval or a hypothesis test question that compares these two means. For example you may want to know if the average weight of a rippled potatoe chip is the same as the average weight of a non rippled potatoe chip. You may weigh rippled...

Write a confidence interval and hypothesis test using the word problem below. I am currently building a home gym in my garage and am not buying calibrated weight plates to reduce the overall budget. I want to know if the average weight of a 45lb steel plate is the same as a 45-lb concrete filled plate. I weighed seven steel plates and find weights of 44.8, 45.3, 45.0, 44.9, 44.7, 45.1, and 45.0lbs. I weighed seven concrete filled plates and...

In this project you will be asked to find confidence interval and perform a hypothesis test for the mean of one population. Be sure to show all your work neatly. Instructions The table provided below contains pulse rates after running for 1 minute, collected from females who drink alcohol ("Pulse rates before," 2013). The mean pulse rate after running for 1 minute of females who do not drink is 97 beats per minute. Do the data show that the mean...

Propose either a confidence interval or a hypothesis test question that compares these two means. For example, you may want to know if the average weight of a rippled potato chip is the same as the average weight of a non-rippled potato chip. You may weigh rippled regular potato chips from a large bag and find weights of 1.7, 1.9, 2.4, 1.3, 1.7, and 2.0 grams. You may weigh non-rippled potato chips from another large bag and find weights of...

In each problem show all steps of the hypothesis test or confidence interval. If some of the assumptions are not met, note that the results of the test or interval may not be correct and then continue the process of the hypothesis test or confidence interaval.
