A student wants to prove that a GMAT prep company's claim that attending its 10-session prep course raises students' scores on the GMAT by an average of at least 50 points is false. In order to test the claim, they take eight students who have previously taken the GMAT and have them complete the 10 sessions. After completion, the students retake the GMAT and their scores are recorded. Test the theory at a 1% level of significance, using the paired difference test. You may assume that the differences in scores are normally distributed.

23A. A health psychologist is interested in whether certain situations produce different amounts of stress. A group of 15 students is randomly assigned to one of three groups. The students in group 1 have their stress levels measured immediately after returning from vacation. The students in group 2 have their stress levels measured after they have been in class for a week. The students in group 3 have their stress levels measured immediately before final exams week. Use this information to complete the ANOVA table provided below.

23B. Using the ANOVA table above, calculate the least biased measure of effect size.

23C. Interpret (in words) the magnitude of effect you computed above.

A 500 nF capacitor is initially connected to a 100 V DC voltage source. At some long time later, the switch is flipped and the capacitor is now connected to a 120 mH inductor.

a) What is the frequency of oscillation in the circuit after the switch is flipped.

b) After the switch is filpped, what would the peak current value be?

c) What is the maximum possible value for the energy stored in the inductor?

d) The energy in an LC circuit oscillates between the inductor and the capacitor. What is the charge on the capacitor when the energy in the inductor is half of its maximum value?

e) The energy in an LC circuit oscillates between the capacitor and the inductor. If I is initially zero when the switch is flipped (t = 0) how much time has elapsed before the energy in the inductor is half of its maximum.

1. A clinical trial was conducted to test the effectiveness of the drug zopiclone for treating insomnia in older subjects. Before treatment with zopiclone, 16 subjects had a mean wake time of 102.8 minutes. After treatment with zopiclone, the 16 subjects had a mean wake time of 98.9 minutes and a standard deviation of 42.3 minutes. Assume that the 16 sample values appear to be from a normally distributed population.

   1. a) Test the claim that after treatment with zopiclone, subjects have a mean wake time of less than 102.8 minutes at the ? = 0.05 level of significance. Use the critical value method. (Show all six steps for hypothesis testing.)

   2. b) Explain what it would mean to make a Type I error.

   3. c) Explain what it would mean to make a Type II error.

A researcher would like to evaluate the effectiveness of a pain-relief patch designed for lower back pain. Prior to testing the patch, each of n = 8 patients rates the current level of back pain on a scale from 1 to 10. After wearing the patch for 90 minutes, a second pain rating is recorded. The data are as follows:

                  Before      After

                        6            2

                        8            3

                        9            4

                        8            1

                      10           2

                        5            3

                        9            8

                        7            7

Mr. Funperson will graduate with an engineering BS degree from USF before his 25th birthday, and start his first professional job immediately upon his graduation. Mr. Funperson decides to set up a retirement account and makes his first monthly deposit into the retirement account a month after his 25th birthday. He will continue making these monthly deposits until he retires at 65. His goal is for his retirement account to reach 500,000 dollars on his 65th birthday. Assume an interest rate of 6% per year.

Calculate Mr. Funperson's monthly deposit if he stops making deposits after his 55th birthday. That is, his last deposit will be made on his 55th birthday.

a.) $248

b.) $274

c.) $299

As part of an interview for a summer job with the Coast Guard, you have been asked to help determine the search area for two sunken ships by calculating their velocity just after an accident. According to the last radio transmission from the luxury liner Apollo (3.9 × 104 metric tons), it was going due east at a steady speed of 21 knots in calm seas through a rare fog just before it was struck broadside by the freighter Blake (6.1 × 104 metric tons), which was traveling north at steady speed of 11 knots. The transmission also noted that when the freighter's bow pierced the hull of the liner, the two ships stuck together and sank. What was the speed and direction of the ships after the collision ? (Take zero degrees to be straight east and counter-clockwise as positive.)

1)____ knots

2)____ degrees
