AAAAAAA Number of People Killed 3.50 300 250 200 150 100 50 0 -50 -100 -150 4 5 6 Magnitude of Earthquake 12 The relationship between the magnitude of the earthquake and the number of people killed is influenced by the country in which the earthquake takes place. Some countries have building codes that produce buildings that better withstand the damage of an earthquake than buildings in some other countries. In this scenario, the country in which an earthquake takes place is which of the following? Extrapolation Outlier Lurking variable Residual Influential Observation 3 7 10 -

The final grade in a particular course is determined by grades on the midterm and final. The grades for five students and the two grading systems are modeled by the following matrices. Call the first matrix A and the second B. Complete parts (a) and (b). Click to view the matrices. a. Describe the grading system that is represented by matrix B. Grading system 1 assigns 50% of the final grade to the midterm and 50% of the final grade to the final. Grading system 2 assigns 20% of the final grade to the midterm and 80% of the final grade to the final. b. Compute the matrix AB and assign each of the five students a final course grade first using system 1 and then using system 2. (89.5-100=A, 79.5-89.4 = B, 69.5-79.4 = C, 59.5-69.4D, below 59.5 = F) Grade System 1 System 2 ... Student 1 Student 2 Student 3 Student 4 Student 5 (Type A, B, C, D, or F.)

Statistics question: a sample of 25 families was taken for a study. the objective of the study was to estimate the factors that determine the monthly expenditure (in dollars) on food for families. the independent variables included in the analysis were the number of members in the family (x1), the number of meals eaten outside (x2), and a dummy variable (x3) that equals 1 if a family member is on a diet and equals 0 if there is no family member on a diet. the following regression results were obtained. coefficients standard error intercept 450.08 53.6 x1 49.92 9.6 x2 10.12 2.2 x3 -.60 12.0 ANOVA df SS MS regression…
