Directions Read the following problem In your dropbox submis

Directions: Read the following problem. In your dropbox 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. 2. A new method of storing snap peas is believed to retain more ascorbic acid than an old method. In an experiment, snap peas were harvested under uniform conditions and frozen in 62 equal-size packages. Thirty five of these packages were randomly selected and stored according to the new method and the other thirty two packages were stored by the old method. Subsequently, ascorbic acid determinations were made, and the following summary statistics were calculated.

                                New method                Old method

Mean                       449                               451

St. dev.                    19                                  45

Sample size             35                                  32

Do these data substantiate the claim that more ascorbic acid is retained under the old method of storing at the 5 % level of significance?
