Using the data from questions 3 and 4 (displayed below), consider the following problem set-up. A physiologist wants to evaluate whether or not a treatment causes an observed measurement to significantly increase.Using a paired t test, the physiologist observes a measurement from 15 participants, administers a treatment, and then takes another measurement to see the impact of the treatment.The research hypothesis is that participants who receive the treatment have an increasein the second observation. The null hypothesis is that there is no difference between the first and second observation.
