Directions Read the following problem In your drop box submi

Directions:           Read the following problem. In your drop box submission, please include the following information:

        a.     Determine if the problem is either a test of hypothesis, a confidence interval or something else and specify the ‘key words’ found in the problem that demonstrate your choice.    

        b.     Determine the procedure name and parameters involved for each problem (use the Stat 200 Formulas and Techniques Summary document.) Specify the ‘key words’ found in the problem that lead you to this choice.

        c.     If the problem is a hypothesis test, indicated if it has a lower-tail, upper-tail, or two-tail alternative hypothesis as well as the test statistic formula for the test. If the problem is a confidence interval then indicate the formula used for the margin of error.

You DO NOT need to do the ACTUAL test of hypothesis, confidence interval, etc. in order to submit in the dropbox, just answer parts a, b, and c for the problem.

      An instructor at Arizona State University asked a random sample of eight students to record their study times in a elementary statistics course. She then made a table for total hours studied over 2 weeks and test scores at the end of the 2 weeks. Here are the data:

Study time             10            15            12            20            8              16            14            22

Test Scores           92            75            86            76            92            80            84            81

                             Assuming that a linear association exists, how are the data correlated? Determine the exact linear relationship between study time and test scores and use it to estimate the predicted test score for a student who studies 12 hours. You DO NOT need to do the ACTUAL test of hypothesis, confidence interval, etc. in order to submit in the dropbox, just answer parts a, b, and c for the problem.
