Practice Test 2 Problem 2

2. A researcher is attempting to analyze her data from a recent lab experiment with 7 participants involving neuroimaging. Currently, she is trying to calculate her degrees of freedom. a. What is the degrees of freedom for her study (she collected data from 7 participants)? (1 point). b. What statistical test is she running (2 or t?)? (1 point). 0. Imagine that she conducted her test and calculated an obtained statistic (t or 2). Her obtained statistic is 2.35 and the corresponding critical value is 2.57. If the researcher rejects the null (that there would be no difference between MD and MI), what type of error is she making? (1 point). Imagine the mill is true in reality
