A researcher is studying the effect of face images on brain activity. She finds a sample of WOU students who agree to go in an fMRI machine. The participants first see a set of faces, while the fMRI measures whether or not there is activity in a key region of interest (yes or no). Then the participants see a set of visual images that don't include faces, and again the fMRI measures brain activity in the same manner. The null hypothesis is that there is no relationship between the type of image viewed and the presence or absence of activity in this brain area. The most appropriate test to analyze the results would be:

Group of answer choices

a. A one-sample t-test

b. An unpaired two-sample t-test

c. A paired two-sample t-test

d. A one-way ANOVA

e. A repeated-measures ANOVA

f. A two-way ANOVA

g. A Pearson's correlation test

h. A chi square test for goodness of fit

i. A chi square test for independence
