The following technology printout provides data on curved carapace (shell) length (in centimeters) for 74 captured turtles. Complete parts a through d below. Descriptive Statistics: Length Variable N Mean StDev Variance Minimum Maximum Range Length 74 57.35 12.18 148.35 31.31 81.95 50.64 (. . . a. Locate the range of the shell lengths on the printout. The range is (Type an integer or a decimal. Do not round.) b. Locate the variance of the shell lengths on the printout. The variance is (Type an integer or a decimal. Do not round.) c. Locate the standard deviation of the shell lengths on the printout. The standard deviation is (Type an integer or a decimal. Do not round.) d. If the target of interest is these specific 74 captured turtles, what symbols would be used to represent the variance and standard deviation? The symbol for the variance would be and the symbol for the standard deviation would be
