- on the basis of the value of linear correlation coefficient, would you conclude, at the /r/>0.9 level, that the data can be reasonably modeled linear equation?Calculate the equation of the regression line and calculate the correlation coefficientfind the (a) explained variation, (b) unexplained variation, and (c) indicated prediction interval. In each case, there is sujficient evidence to support a claim of a linear correlation, so it is reasonable to use the regression equation when making predictions. Altitude and Temperature Listed below are altitudes (thousands of feet) and outside air temperatures (°F) recorded by the author during Delta Flight 1053 from New Orleans to Atlanta. For the prediction interval, use a 95% confidence level with the altitude of 6327 ft (or 6.327 thousand feet).
- The coefficient of determination of a set of data points is 0.842 and the slope of the regression line is −3.56. Determine the linear correlation coefficient of the data.State the four conditions required for making regression inferences.If two regression coefficients are 2.4 and 0.4 then what would be the value of coefficient of correlation.
