2. Management training programs are often instituted to teach supervisory skills and thereby increase productivity. Suppose a university psychologist administers a set of examination to each of 10 graduating students before such training program begins and then administers similar examinations at the end of the program. Examinations are designed to measure supervisory skills, with highest scores indicating increased skills. The results are shown below: Student After Training Before Training 1 63 78 2 93 92 3 84 91 72 80 65 69 72 85 91 99 8 84 82 9 71 81 10 80 87 Do the data provide evidence that the training program is effective in increasing supervisory skills, as measured by the examination scores? Use 0.10 significance level. (critical value = +1.383) 45678

ANOVA. Dr. Milgramm is conducting a patient satisfaction survey, rating how well her patients like her on a scale of 1-10. Her patients tend to fall into three categories: “Like a lot”, “like somewhat”, and “dislike a lot”. She believes that she might get different satisfaction scores from people in each group, but (because she's not great at numbers) she wants you to do an ANOVA to be sure. She has collected data from 12 patients (three equal groups) with the following results.   Group 1) “Like a lot”               Mean:   8                    SS: 2   N:                    df:            Group 2) “Like somewhat”     Mean:   5                    SS: 6   N:                    df:             Group 3) “Dislike a lot”         Mean:    2                   SS: 4   N:                    df:              Grand Mean:          df Within-Group:__________ df Between-Groups:___________   Estimated Variance (S21) for Group 1: _______ Estimated Variance (S22) for Group 2: ___________ Estimated…

2. A researcher conducts a study examining the effectiveness of a group exercise program at an assisted living facility for elderly adults. One group of residents is selected to participate in the program, and a second group serves as a control. After 6 weeks, the researcher records a combined score measuring balance and strength for each individual. The data are as follows: Control n = 10 M = 12 SS = 120.5 Exercise n = 15 M = 15.5 SS = 190.0 Conduct the four steps for hypothesis testing and label a. Use a two-tailed test with a = .05. each step: Step1, Step 2, Step 3, and Step 4. b. Calculate Cohen's d. c. Are the data sufficient to conclude that thier is a significant difference? Write your answer in the form of a sentence.

Government economic studies reveal that young adults, not middle-aged or older adults, are having the most difficult time in today’s economy. Although the nation’s labor market shows a decline in the unemployment rate, the percentage of young adults, ages 18 to 24, currently employed (54 percent) is at the lowest level since the government data collection began in 1948. If you were working for a national survey organization doing a general public survey of young adults and older adults, what topics and questions would you design into your survey to elaborate on this finding?
