A community health center tracks the number of flu-related visits during each month to see whether there is a 'fluseason' at a particular time of year. They also want to test whether this pattern is the same for people in cold-winterstates (ex. WI, MN) compared to people in warm-winter states (ex. CA, FL, AZ).O chi-square for independenceO multiple regressionOtwo-way independent-measures ANOVAO point-biserial correlation

Question 5 Consider a two way-factorial ANOVA with two factors: homework and test anxiety. Homework has two categories (prepared homework vs. did not prepare) and so has test anxiety (test anxiety vs. no text anxiety). Homework and test anxiety are used to predict the continuous outcome variable test score. The statistical model includes significant main effects and a significant interaction effect. Indicate for each of the statements whether it is correct. Correct Incorrect The difference in test scores between pupils with and without test anxiety differs between those who prepared their homework and those who did not. The effect of having prepared homework on test scores differs across pupils who have test anxiety and pupils who do not have test anxiety.

Researchers investigate how the presence of cell phones influence the quality of human interaction. Subjects are randomly selected from a population and divided into an experimental group that is asked to leave their phones in the front of the room and a control group that are not asked to leave their cell phones at the front of the room. Subjects are left alone for 10 minutes and then asked to take a survey designed to measure quality of interactions they had with others in the experiment. What statistical test is appropriate?
