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. VarianceC. Standard Deviation

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.

“Is the following measure a Statistic or a Parameter: ‘The measurement of the heights of all mature redwood trees in the Redwood National Forest.'”

“Describe the following data as Qualitative or Quantitative and explain why: A. The species of trees in an old-growth forest (e.g., oak, maple, pine, etc.)B. The heights (in meters) of the trees in the same forest.”
