In Exercises 520, find the range, variance, and standard deviation for the given sampledata. Include appropriate units (such as minutes) in your results. (The same data wereused in Section 3-2 where we found measures of center. Here we find measures of variation.)Then answer the given questions. Cell Phone Radiation Listed below are the measured radiation emissions (in W/kg)corresponding to these cell phones: Samsung SGH-tss9, Blackberry Storm, Blackberry Curve,Motorola Moto, T-Mobile Sidekick, Sanyo Katana Eclipse, Palm Pre, Sony Ericsson, Nokia6085, Apple iPhone 3G S, and Kyocera Neo E1100. The data are from the EnvironmentalWorking Group. If one of each model of cell phone is measured for radiation and the resultsare used to find the standard deviation, is that standard deviation equal to the standard deviationof the population of all cell phones that are in use? Why or why not?0.38 0.55 1.54 1.55 0.50 0.60 0.92 0.96 1.00 0.86 1.46
