1: (a) Option is correct, because here Two factor occur and first facor has 4 level of treatments and second factor has 2 level of treatments.
2:(c) Option is correct because here we use 2-way ANOVA analysis and for this we write 2 Null , it means two two test that is for both facor.

Question 1 (6 points) Two college instructors are interested in whether or not there is any variation in the way they grade math exams. They each grade the same set of 10 exams. The first instructor's grades have a variance of 59.2. The second instructor's grades have a variance of 72.5. Test the claim that the first instructor's variance is smaller. (In most colleges, it is desirable for the variances of exam grades to be...

4. Repeated-measures ANOVA Aa Aa Suppose you are interested in studying whether lighting brightness affects spatial reasoning abilities. You decide to test spatial reasoning using completion time scores for the paper-folding test with five people, repeating the test on each person with three different lighting levels (800, 1,000, and 1,200 lux) In this experiment, the null hypothesis is that: O There are no individual differences in the completion time means O The completion time mean for at least one lighting...

1 A researcher wants to find out which type of classroom instruction significantly improves students’ test performance. He designed four types of instruction for four samples of students. Later all four samples were given the same test and their average performance was compared. What statistical test should be used by the researcher to analyze the results of this study? A. Pearson correlation B. t-test for independent groups C. one-factor Anova for between groups D. Chi2 for Independence 2 A researcher...

gretl: model 1 File Edit Tests Save Graphs Analysis LaTeX Question 5 In your first year microeconomics course you learned about differentiated products. As an econometrics student differentiated products are interesting because they are prime candidates for hedonic price modelling. As mentioned in class, a hedonic price model is a regression model that relates the price of a differentiated product (a residential house in this case) to its characteristics. For this assignment you will construct a simple hedonic model for...
