What is another name for the standard deviation of the variable x? What is the reason for that name?

When using 1-Var Stats on a scientific or graphing calculator, the resulting statistical output includes two values for the standard deviation of the data set.  These values are labeled as Sxand σx in the statistical output.  Why is it necessary to give two values for the standard deviation?  How would you choose which one to use as the standard deviation of a data set you are working with?  Be sure to explain the difference between these two values as you answer these questions

How much data is between 1 standard deviation of the mean? There are approximately     (answer) % of the data is between 1 standard deviation of the mean.

A queueing system has an arrival rate of 37 visitors per day (standard deviation of 32) and a service rate of 42 visitors per day (standard deviation of 25). (Round your answer to three decimal places.) What is the coefficient of variation of the arrival rate?

How to find the standard deviation after we have found the range?

what estimate does the range rule of thumb give you for the standard deviation?

In a test, the average of the grades is 80 and the standard deviation is 5. John's grade is 70, so his grade is standard deviations the average. 2 below 10 --------- below 70 above equal to
