Math 40 Homework Assignment 7 1. Fitting a straight line to a set of data yields the following prediction line: Y=2+5x a. Interpret the meaning of the y intercept, bo b. Interpret the meaning of the slope, b1 c. Predict the value of y for x= 3 2. If the values of x in problem range from 2 to 25, should you use this model to predict the mean value of y when x = a. 3? b. -32 C. 0 ? d. 24 ? 3. Fitting a straight line to a set of data yields the following prediction line: Y = 16 - .05x a. Interpret the meaning of y intercept, bo b. Interpret the meaning of slope, b1 c. Predict the value for y when x = 6 4. How do you interpret a coefficient of determination, r2 = 0.80? 5. If SSR = 36 and SSE = 4 determine SST and compute the coefficient r2 and interpret its meaning. 6. If SSR = 66 and SST = 88 compute the coefficient r2 and interpret its meaning. 7. If SSE = 10 and SSR = 30 determine SST and compute the coefficient r2 and interpret its meaning 8. If SSR = 120, why is it impossible for SST to = 110? h (United States) { Accessibility: Good to go EG Focus
