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.

- A real estate major collected information on some recent local home sales. The first 6 lines of the database appear in the accompanying table. The columns correspond to the house identification number, the community name, the zip code, the number of acres of the property, the year the house was built, the market value, and the size of the living area (in square feet).

The data in the “HW7.xlsx” file on Moodle shows a portion of the data for a sample of 20 of the companies that made the top 100 list for 2012. The column labeled Rank shows the rank of the company in the Fortune 100 list. The column labeled Size indicates whether the company is a small (fewer than 2500 employees), midsize (2500-10,000 employees) or large company (above 10,000 employees). The column labeled Salaried ($1000s) shows the shows the average annual salary for salaried employees rounded to the nearest $1000. Finally, the column labeled Hourly ($1000s) shows the average annual salary for hourly employees rounded to the nearest $1000. a) Use these data to develop an estimated regression equation that could be used to predict the average annual salary for salaried employees given the average annual salary for hourly employees. b) Use ? = 0.05 to test for overall significance.
