The authors of a paper titled "Age and Violent Content Labels Make Video Games Forbidden Fruits for Youth" carried out an experiment to determine if restrictive labels on video games actually increased the attractiveness of the game for young game players. Participants read a description of a new video game and were asked how much they wanted to play the game. The description also included an age rating. Some participants read the description with an age restrictive label of 7+,...

Please help to do these questions, Thank you so much! Three different brands of tires were compared for wear characteristics. From each brand of tire, ten tires were randomly selected and subjected to standard wear-testing procedures. The average mileage and the sample standard deviation (both in 1000 miles) obtained for each brand of tire are shown below. The overall mean is 36. 2) Brand C | Brand A | Brand B Average Mileage37 Sample Variance 38 What are the numerical...
Please help with the following multiple choice 1. In the one-way ANOVA where there are k treatments and n observations, the degrees of freedom for the F-statistic are equal to, respectively: a. n and k. b. k and n. c. n − k and k − 1. d. k − 1 and n − k. 2. In ANOVA, the F-test is the ratio of two sample variances. In the one-way ANOVA (completely randomized design), the variance used as a numerator...
The problemesenpoon indicates that the samples samples. For these reasons, it is reasonable to condude that the conditions are met. Step 6 Recall that when the conditions for a single factor ANOVA F test for equality of three or more means are met. and the null hypothesis, Ho: , -, , , is true, we use the following test statistic where df, - k-1, df, -N-k MST is the mean square of treatments, MSE is the mean square of errors,...
A major television network is considering three potential situation comedies: Bobby's Bunch, My Ex-Husbands, and I Like Larry. A pilot ("first") episode for each has been taped. The network is trying to determine whether some shows are better liked than others and whether younger viewers (under age forty) tend to have different opinions than older viewers (age forty and above). The network randomly selected 30 people under age forty and 30 people age forty and above. It randomly divided those...

1. (55 points) The investigators are interested in asses the relationship between Systolic Blood Pressure (SBP) in mm Hg and Age in years among Hypertensive Patients. Specif- ically, whether a patient's SBP can be predicted from his or her age. They selected n=122 patients at random from a medical record database in a hospital. Assume that the simple linear regression model is appropriate. The following table shows regression output of a simple linear regression model relating the SBP to the...
