My intended future career is to be a nurse. Give an example of a mean that applies to two populations for which you would like to do a hypothesis test in nursing. In this hypothesis test you will be testing the difference between these two population means when the two samples are independent. Your discussion must include the two target populations along with the population characteristic that you’re mean is computed for and the unit that is used when taking...

The following numbers are the differences in pulse rate (beats per minute) before and after running for 12 randomly selected people. Positive numbers mean the pulse rate went up. Test the hypothesis that the mean difference in pulse rate was more than 0,using a significance level of 0.05. Assume the population distribution is Normal 22,8,11,12,15,7,0,2,9,39,1, and 13 Determine the null and alternative hypotheses.

Suppose Diana, an educational researcher at a local university, wants to test the impact of a new Spanish course that integrates cultural-immersion teaching techniques with standard teaching practices. She selects a simple random sample of 72 freshmen and divides them into 36 pairs, matched on IQ and high school GPA. She randomly selects one member of each pair to take the new course, while the other member in the pair takes the traditional course. Next, Diana records the course grade,...

You would like to know whether there is a difference between the rate of cooling of freshly killed corpses versus those that were reheated (to determine if you could fool a coroner about time of death). You tested several rats for their cooling constant, both when the rat was freshly killed and after the same rat was reheated. Assuming the distribution of differences is normal, is there any difference in the cooling constants between freshly killed and reheated rats? Use...
