You definelow media exposure as 0-5 hours/week, medium exposure as 6-10 hours/week and high exposure as morethan 10 hours/week.You randomly sample 400 adults and find that 175 have a high school education, 140 have college as theirhighest level of education, and 85 have a postgraduate degree (e.g., JD, MA, MPA, DDS, Dr., Ph.D.). Ofthose with a high school education, 72 have low levels of media exposure, 40 have medium levels of mediaexposure, and 63 have high levels of media exposure. Of those with a college degree, 45 have low levelsof media exposure, 45 have medium levels of media exposure, and 50 have high levels of exposure.

Of particular interest were the percentages of female faculty in the College of Education and in the College of Business . In a sample of 80 College of Education faculties, there were 36 females, and in a sample of 70 College of Business faculties, there were 15 females. Based upon this sample information, which of the following is the 98% confidence interval for the difference in the actual percentages of female faculty between College of Education and College of Business ? a. (0.075, 0.405). b. (0.123, 0.357). c. (-0.012, 0.252). d. (0.058, 0.422). e. (0.101, 0.379).
The concept “Job Involvement” is defined as the degree to which an employee is engaged in and enthusiastic about performing his/her work.

A biologist is studying the composition of birds on a lake and counts 61 ducks, 17 geese, 11 cranes, 15 swans, and 6 herons. From previous studies performed around the same time of the year, she expects 50% of the birds to be ducks, 23% to be geese, 12% to be cranes, 10% to be swans, and 5% to be herons. What are the expected and observed counts? Select one.

Twenty-nine college students, identified as having a positive attitude about Mitt Romney as compared to Barack Obama in the 2012 presidential election, were asked to rate how trustworthy the face of Mitt Romney appeared, as represented in their mental image of Mitt Romney’s face. Ratings were on a scale of 0 to 7, with 0 being “not at all trustworthy” and 7 being “extremely trustworthy.” Here are the 29 ratings: 2.6 3.2 3.7 3.3 3.4 3.6 3.7 3.8 3.9 4.1 4.2 4.9 5.7 4.2 3.9 3.2 4.5 5.0 5.0 4.6 4.6 3.9 3.9 5.3 2.8 2.6 3.0 3.3 3.7 a 95% confidence interval for the mean rating.
