3. What are the effects of repeated exposure to an advertising message? An experimentinvestigated this question using a random sample of households who regularly watchtelevision. All subjects viewed a 30-minute television program that included ads for a newvideo camera. Some subjects saw a 30-second commercial, others a 90-second version. Thesample commercial was repeated either one, three, or five times during the program. Afterviewing, all of the subjects answered questions about their recall of the ad, their attitudetoward the camera, and their intention to purchase it. For this experiment, four subjects wererandomly assigned to each treatment combinations of length of commercial and number ofrepetitions of the commercial. For this experiment,a) Name the experimental units.b) Name the response variable(s).c) Name the factor(s) or explanatory variable(s) and how many levels each factor has.d) List 3 different possible treatments.e) How many subjects were needed for the experiment (think about how many treatmentsthere are total)?

A report summarizing scores for students on a verbal aptitude test x and a math aptitude test y gives the following results: x = 480, sx = 80, y = 500, sy = 120, r = 0.6.
Dr. Peart randomly assigns some children to two separate groups. One group of children watches a video of an adult "beating" a doll. The other group watches a video of the same adult playing with the doll. After the video, each child is given a doll and the researchers observed what they did with the doll. In this case, the independent variable is: i. What is the independent variable and dependent variable in this study? Name the conditions in the independent variable. ii. If Dr. Peart wants to have 10 children in each condition, what is the total number of kids that she needs?
A consumer group wanted to determine if there was a difference in customer perceptions about prices for a specific type of toy depending on where the toy was purchased. In the local area there are three main retailers: W-Mart, Tag, and URToy. For each retailer, the consumer group randomly selected 5 customers, and asked them to rate how expensive they thought the toy was on a 1-to-10 scale (1= not expensive, to 10 = very expensive). The toy was priced the same at all retail stores. Compute the percentage of variance explained by the group differences for these data. Q: Percentage and variance explained = ?

A psychologist would like to examine the effects of a new drug on the activity level of animals. Three samples of rats are selected with n=5 in each sample. One group gets no drug, one group gets s small dose, and the third group gets a large dose. The psychologist records the activity level for each animal. The data from this experiment are presented below. No drug Small dose Large dose 5, 3 , 1 , 1 , 5 5, 5, 9, 6, 5 10, 12, 9, 6, 8 =3, SS=16 =6, SS=12 =9, SS=20 Do these data indicate any significant differences among the three groups? Test with α=0.05. Compute the effect size and interpret the result.
he federal government is interested in determining whether salary discrimination exists between men and women in the private sector. Suppose a sample of 16 women and 25 men are taken from the population of first-level managers in the private sector. The information is summarized as follows (amounts are in thousands of dollars): Women Men n 16 25 X¯ $26.4 $33.3 S $2.6 $3.2 Test H0 : µ1 = µ2 against H1 : µ1 = µ2 where µ1 and µ2 are the mean salary of first level female and male managers, respectively. Use α = 0.05 and assume equal variances.
