A health psychologist claims that the more final exams a student has during finals weeks, the more stressed they are. They want to test this experimentally by having 100 students receiving additional finals in their fall semester and then assessing each participants stress during finals ( = mu1). Then the same 100 students receive no additional finals in their spring semester and are assessed on their stress during finals ( = mu2) and they want to assess if the difference in stress with no additional finals relative to additional finals with mu2 - mu1. = mu1 = Additional finals and = mu2 = No additional finals What would be the null and alternative hypotheses?

A health psychologist claims that the more final exams a student has during finals weeks, the less sleep they get.

A health psychologist claims that the more final exams a student has during finals weeks, the more stressed they are. They want to test this experimentally by having 25 students receiving no additional finals in their fall semester and then assessing each participants stress during finals ( = mu1). Then the same 25 students receive additional finals in their spring semester and are assessed on their stress during finals ( = mu2) and they want to assess if the difference in stress with no additional finals relative to additional finals with mu1 - mu2. = mu1 = No Additional finals and = mu2 = Additional finals We find our t-statistic to be -2.16, so our conclusion should be: Please enter 1 for reject the null hypothesis Please enter 2 for fail to reject the null hypothesis
A health psychologist claims that the more final exams a student has during finals weeks, the more stressed they are. They want to test this experimentally by having 418 students receiving no additional finals in their fall semester and then assessing each participants stress during finals ( = mu1). Then the same 418 students receive additional finals in their spring semester and are assessed on their stress during finals ( = mu2) and they want to assess if the difference in stress with no additional finals relative to additional finals (mu1 - mu2). = mu1 = No Additional finals and = mu2 = Additional finals What would the degrees of freedom be for this research?
