MAT 210 Unit 4 Milestone 4 (1) QUESTIONS AND CORRECT DETAILED ANSWERS WITH RATIONALES VERIFIED ANSWERS ALREADY GRADED A+.

Which of the following set of statements is true? ● About 94% of the variation in beach visitors is explained by a negative linear relationship with daily temperatures. ● The correlation coefficient, r, is 0.969. ● About 94% of the variation in beach visitors can be explained by a positive linear relationship with daily temperature. ● The correlation coefficient, r, is 0.969. ● About 94% of the variation in daily temperature can be explained by a positive linear relationship with beach visitors. ● The correlation coefficient, r, is 0.880 ● There is no strong correlation in the linear association between beach visitors and daily temperatures. ● The correlation coefficient, r, is 0.880 RATIONALE The coefficient of determination measures the percent of variation in the outcome, y, explained by the regression. So a value of 0.9382 tells us the regression with temperature, x, can explain about 94% of the variation in visitors, y
