Listed below are the recorded battery life durations (in hours) of 14 different laptop models tested under similar conditions. Find the range, variance, and standard deviation for the given sample data. Include appropriate units in your results. (Be sure to use the correct formula between Sample and Population for parts b and c.) Battery Life (hours):6.5, 7.2, 5.8, 8.1, 3.0, 4.5, 5.2, 6.0, 7.8, 8.5, 6.3, 4.8, 3.0, 3.0, 3.0 A. RangeB.

Given the following Data set (2,11)(3,19)(4,10)(5,8)(6,2)(7,5)(9,25)(12,56)   Perform a Linear Regression  A. Report the Model Equation (in the form y = mx+b) for the data set. (round to the nearest hundredth) B. Report the r value C. Does the data set appear to follow a linear relation (is a linear regression a good tool to use on the data set), why or why not.
