- A researcher would like to use a factorial study to compare two programs designed to help people stop smoking. The smoking behavior of each participant will be measured at the beginning of the program, at the end of the program, and again 4 months after the program has ended. Thus, the two treatment program make up one factor, three measurement times make up the second factor. For this study, which factor (s) should be between subjects and which should be within subjects?An experimenter was interested in the effects of three types of therapy and gender on a measure of quality of life. She designed the experiment so that the male subjects were randomly assigned to the different therapies and the female subjects were also randomly assigned to the different therapies. The type of therapy was experimentally manipulated and after six months the outcome was measured. A two-factor design was used. How many independent variables are there in this design? Name each factor (using appropriate descriptors from the paragraph) How many total groups (cells) are there in this design? Name the dependent variable:Kelsey is interested in how students learn different subjects through games or in traditional classroom formats. She thinks that the effect of learning through a game vs. a traditional format might differ based on subject. She designs a 2 x 2 factorial within-subjects experiment in which participants learn introductory algebra and introductory music, with one lesson of each being taught though a game, and one taught in a traditional classroom setting.

- There is an interest in finding a gasoline additive that reduces nitrogen oxides in the exhaust gases. Four types of gasoline additives (A,B,C,D) are available. Two perturbing factors in the experiment are the cars and the drivers. A Latin square was performed for this study as follows: four cars (1,23,4) and four drivers (1,2,3,4) were used to study the possible differences between the four additives (A,B,C,D). The response variable is a coded measurement of the reduction of nitrogen oxides.The results are shown in the following table: (IMAGE) a) Analyze the data from this experiment or to evaluate the effect of different types of gasoline additive. Develop from the ANOVA table and use an α = 0.05. b) Compare the four types of additives using fisher's α=0.05 test. c) The cost of the four additives A, B, C, and D are $1, $2, $3, and $0.50 respectively. If the quality of the nitrogen oxides is to be minimized, which additive would you recommend?A study was conducted to determine the effects of sleep deprivation on subjects' ability to solve simple problems. A total of 5 subjects participated in a study. After his or her sleep-deprivation period, each subject was administered a set of simple addition problems and the number of errors was recorded.

- A dairy farmer thinks that the average weight gain of his cows depends on two factors: the type of grain that they are fed and the type of grass that they are fed. The dairy farmer has four different types of grain from which to choose and three different types of grass from which to choose. He would like to determine if there is a particular combination of grain and grass that would lead to the greatest weight gain on average for his cows. He randomly selects three one-year-old cows and assigns them to each of the possible combinations of grain and grass. After one year he records the weight gain for each cow (in pounds) with the following results. Is there sufficient evidence to conclude that there is a significant difference in the average weight gains among the cows for the different types of grain?

In particular, they were interested in the loudness of the screams (soft versus loud) and the length of the screams (short versus long). They used a 2 × 2 factorial design to test how these factors combined. They collected data from 10 different riders in each of the four conditions. Each rider rated the scariness of the ride on a nine-point scale. short screams long screams soft screams T=38, n = 10, SS = 13.6 T=64, n = 10, SS = 22.4 loud screams T=52, n=10, SS = 29.6 T=50, n=10, SS = 16.0 For these data: G = 204, N = 40, X2 = 1156. 1. Sketch a dataplot of the mean rating in each condition. 2. Calculate SS total, the total sum of squares 3. Calculate SSwithin, the within-treatments sum of squares. 4.

- The number of flaws in a 1-inch length of copper wire manufactured by a certain process varies from wire to wire. Overall, 48% of the wires produced have no flaws, 39% have one flaw, 12% have two flaws, and 1% have three flaws. Let ? be the number of flaws in a randomly selected piece of wire. Then ?(?=0)=0.48, ?(?=1)=0.39, ?(?=2)=0.12, ?(?=3)=0.01. Let ?(?) denote the cumulative distribution function for the random variable ? that represents the number of flaws in a randomly chosen wire.a. Find ?(2).b. Find ?(1.5).c. Determine the cumulative distribution function ?(?). Hint: your answer should be a piecewise function with the following categories: ??<0, 0≤??<1, 1≤??<2, 2≤??<3, ??≥3.d. Plot ?(?).An experiment was done on painting classroom chairs. The results of the experiment is in the following table: No. of students doing the painting 1 2 3 4 No. of tables painted in four hours 1 4 9 16 If the number of students were doubled, will the number of chairs that will be painted be doubled, tripled, or quadrupled?In an experiment examining human memory, two groups of participants are used. One group is allowed 5 minutes to study a list of 40 words and the second group is given 10 minutes of study time for the same list of words. Then, both groups are given a memory test, and the researcher records the number of words correctly recalled by each participant. For this experiment, identify the independent variable and the dependent variable.
