The range of the sample data is (Round to three decimal places as needed.) Sample standard deviation =D (Round to three decimal places as needed.) Sample variance = O (Round to three decimal places as needed.) If one of each model is measured for radiation and the results are used to find the measures of variation, are the results typical of the population of cell phones that are in use?

Question
Find the range, variance, and standard deviation for the given sample data. Include appropriate units in the results. Listed below are the measured radiation absorption rates (in W/kg) corresponding to various cell phone models. If one of each model is measured for radiation and the results are used to find the measures of variation, are the results typical of the population of cell phones that are in use? 1.03 1.29 0.91 0.77 1.01 1.36 1.45 1.47 0.88 0.64 0.64 The range of the sample data is (Round to three decimal places as needed.) Sample standard deviation = (Round to three decimal places as needed.) Sample variance = | (Round to three decimal places as needed.) If one of each model is measured for radiation and the results are used to find the measures of variation, are the results typical of the population of cell phones that are in use? O A. Yes, because the results from any sample of cell phones will be typical of the population. O B. No, because some models of cell phones will have a larger market share than others. Measures from different models should be weighted according to their size in the population. C. Yes, because each model is being represented in the sample. Any sample that considers all possible cell phone models will produce results typical of the population of cell phones. O D. No, because it is necessary to have at least 5 of each cell phone in order to get a meaningful result. Only including one of each cell phone model is not representative of each cell phone model.
