health psychologist claims that final exams will increase stress. They want to test this experimentally by having 56 students receive additional finals in their fall semester and then assessing each participants stress during finals ( = mu1). Then the same 56 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 mu1 - mu2. = mu1 = Additional finals and = mu2 = No additional finals What would be the critical t-value for this research?

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?

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 more stressed they are. They want to test this experimentally by randomly assigning 100 students to receive additional final exams and then assessing motivation, and another 100 students receive no additional final exams and are assessed on their motivation. = mu1 = Additional finals and = mu2 = No additional finals What would be the null and alternative hypotheses? Please select all that apply. Answer choices [H1, p not equal to 0 | H0, P = 0] [H1, p > 0 | H0, P < or = 0] [H1, mu2 - mu1 < 0 | H0, mu2-mu1> or equal to 0] [H1, mu2 - mu1 not equal to 0, H0, mu2-mu1= 0] [H1, mu2 - mu1 > 0 | H0, mu2-mu1 < or equal to 0] [H1, mu1 - mu2 > 0 | H0, mu1-mu2 < or equal to 0] [H1, mu1 - mu2 < 0 |H0, mu1-mu2 > or equal to 0] [H1, mu1 - mu2 not equal to 0 | H0, mu1-mu2 = 0] [H1, p< 0 |H0,p > or equal to 0]
