Measures of Regression and Prediction Intervals Finding the Coefficient of Determination and the Standard Error of Estimate In Exercises 11-20, use the data to (a) find the coefficient of determination r² and interpret the result, and (b) find the standard error of estimate se and interpret the result. 17. Wheat The table shows the quantity of wheat (in millions of kilograms per year) produced by India and the quantity of wheat (in millions of kilograms per year) exported by India for seven years. The equation of the regression line is ? = 0.249x - 19023. (Source: IndexMundi) Produced, x 69355 75807 78570 80679 80804 86874 94882 Exported, y 94 49 23 58 72 891 6824

Step 1
Mean of x values (produced wheat): (69355 + 75807 + 78570 + 80679 + 80804 + 86874 + 94882) / 7 = 81010 Mean of y values (exported wheat): (94 + 49 + 23 + 58 + 72 + 891 + 6824) / 7 = 1158.43 Show more…

Linear Regression In an area of the Midwest, records were kept on the relationship between the rainfall (in inches) and the yield of wheat (bushels per acre). Below is the data: (Round to four decimal places). Rain fall (in inches), x: 10.5, 8.2, 13.4, 12.5, 18.8, 10.9, 7.0, 15.6, 16.0 Yield (bushels per acre), y: 50.5, 46.2, 58.6, 59.0, 82.4, 49.2, 31.9, 76.0, 78.9 a. Find the Regression equation: ŷ = b. Find the coefficient of correlation: c. Find the coefficient of determination: d. What is the predicted value for y given x = 16? e. What is the predicted value for y given x = 6.5? f. Find the standard error of estimate for the data:

Simple linear regression An engineer used a random sample of n = 8 observations on a response variable, y, and a predictor variable, x, to estimate a simple linear regression model. The observations are given in the table below, together with some quantities calculated from the data and the model fit. Use the sample quantities to answer the following questions: (a) Estimate the intercept ̠₀ and slope ̠‑ regression coefficients. (b) Write the estimated regression line equation and interpret it. (c) Estimate for the variance of the error term, ̢². (d) Compute the coefficient of determination R² and explain the meaning of its value.
