Compute and Interpret the Coefficient of Determination
Question
A scientific study on calorie intake gives the following data table.
| Calorie intake (1000) | Weight gained (Ounces) |
|---|---|
| 70 | 28 |
| 72 | 34 |
| 76 | 23 |
| 80 | 24 |
| 84 | 13 |
Using technology, it was determined that the total sum of squares (SST) was 237.2, the sum of squares regression (SSR)was 177.96, and the sum of squares due to error (SSE) was 59.244. Calculate R2 and determine its meaning. Round your answer to four decimal places.
Select the correct answer below:
R2=0.2498
Therefore, 24.98% of the variation in the observed y-values can be explained by the estimated regression equation.
R2=0.7503
Therefore, 75.03% of the variation in the observed y-values can be explained by the estimated regression equation.
R2=1.3329
Therefore, 13.329% of the variation in the observed y-values can be explained by the estimated regression equation.
R2=0.3329
Therefore, 33.29% of the variation in the observed y-values can be explained by the estimated regression

2. Multiple coefficient of determination Aa Aa Macroeconomics is the study of the economy as a whole. A macroeconomic variable is one that measures a characteristic of the whole economy or one of its large-scale sectors. In forecasting the sales of a product, market researchers frequently use macroeconomic variables in addition to marketing mix variables (marketing mix variables include product, price, place [or distribution], and promotion) A market researcher is analyzing an existing multiple regression model that predicts sales for...

The following data show the brand, price ($), and the overall score for six stereo headphones that were tested by a certain magazine. The overall score is based on sound quality and effectiveness of ambient noise reduction. Scores range from 0 (lowest) to 100 (highest). The estimated regression equation for these data is ŷ = 20.455 + 0.335x, where x = price ($) and y = overall score. Brand Price ($) Score A 180 78 B 150 69 C 95...
