Question

The arm span and foot length were both measured (in centimeters) for each of 20 students in a biology clas. The computer output displays the regression analysis.

Which of the following represents the standard deviation of the residuals?
A.0.035
B.0.186
C.1.61
D.2.567

Answer 1

The standard deviation of the residuals is given as s = 16.4 from a LinRegTTest calculator function, which does not match any of the provided options.

Step-by-step explanation:

The standard deviation of the residuals in a regression analysis is represented by the value s. Based on the provided information, the calculator function LinRegTTest found s = 16.4 as the standard deviation of the residuals for a dataset. Thus, when you are looking at the options provided (A. 0.035, B. 0.186, C. 1.61, D. 2.567), none of these match the given value of s = 16.4. So in this context, these options do not represent the standard deviation of the residuals.

The standard deviation of the residuals can be determined from the computer output of the regression analysis. Look for a value labeled 'Standard Error of the Residuals' or 'Residual Standard Deviation' in the output.

In this case, the options provided are A. 0.035, B. 0.186, C. 1.61, and D. 2.567. Without the actual computer output, it is not possible to determine which option represents the standard deviation of the residuals.
