7. A psychologist is interested in determining whether immediate memory capacity is affected by sleep loss. Immediate memory is defined as the amount of material that can be remembered immediately after it has been presented. Twelve students are randomly selected from lower division college courses and randomly assigned to two groups of 6 each. One of the groups is sleep deprived for 24 hours before the material is presented. All subjects in the other group receive the normal amount of sleep (7-8 hours). The material consists of a series of slides, with each slide containing nine numbers. Each slide is presented for a short time interval (50 milliseconds), after which the subject must recall as many numbers as possible. On the following page are the results. The scores represent the percentage correctly recalled. Normal Sleep Group: 68 73 72 65 70 73 Sleep Deprived Group: 70 62 68 63 69 60

a. Describe (1) the independent variable and its levels, and (2) the dependent variable and its scale of measurement. Independent Variable- immediate memory capacity is affect by sleep Dependent- Variable- Scores represent the percentage correctly recalled between two groups b. Describe the null and alternative hypotheses for the study described. c. Using Excel, conduct a statistical test of the null hypothesis at p = .05. Be sure to properly state your statistical conclusion. d. Provide an interpretation of your statistical conclusion in part C. e. What type of statistical error might you have made in part C? f. Obtain the 95% confidence interval using the obtained statistic. g. Provide an interpretation of the confidence interval obtained in part f. h. Does the confidence interval obtained support your statistical conclusion? Explain your answer.

suppose that you are tossing two six sided dice one by one. What is the probability that (a) you will observe a total of 10? (b) You will observe a six on any dice? (c) You will observe a total at most of 7? (d) You will observe at least 11?

Sana had two equal outstanding loans, one from 135 days ago and one from 81 days ago. She repays both loans today with the single amount of $14800. If interest is 7% on the loans, what was the size of the equal amounts borrowed?

1. MUST USE SPSS AND POST RESULTS. A researcher is interested in studying the effect that the amount of fat in the diet and amount of exercise has on the mental acuity of middle-aged women. The researcher used three different treatment levels for the diet and two levels for the exercise. The results of the acuity test for the subjects in the different treatment levels are shown below.

1. Perform a Two-way analysis of variance (ANOVA) and report the results using correct APA style; report whether significance was found for Factor A, Factor B, and/or an interaction between Factors A and B was found.
2. If the test statistic is significant, run a post hoc test to determine between what groups significance was found.
3. Report an effect size for all significant results.

Miami Mutual Bank* purchases a two-year interest rate cap for a fee of 3 percent of notional principal valued at $10 million, with an interest rate ceiling of 11 percent and LIBOR as the index representing the market interest rate. At the same time, Miami Mutual sells a two-year floor (8 percent) for a fee of 2 percent of the $10 million principal. Assume that LIBOR is expected to be 7 percent and 14 percent at the end of each of the next two years, respectively. What is this type of strategy called? Also what do dollar amount do Miami Mutual Bank stand to gain or lose from this strategy?
