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? 0.950.950.730.730.630.630.910.911.3 21.321.481.480.630.631.231.230.910. 911.411.410.670.67the range of the sample data isnothing▼(round to three decimal places as needed.)sample standarddeviationequals=nothing▼kg. kg. left parenthesis upper w divided by kg right parenthesis squared .w/kg2.w. w.upper w divided by kg. w/kg.(round to three decimal places as needed.)samplevarianceequals=nothin g▼kg. kg. left parenthesis upper w divided by kg right parenthesis squared .w/kg2.upper w divided by kg. w/kg. w.w.(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? a. 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. b.yes, because the results from any sample of cell phones will be typical of 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. d.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.

The table shows population statistics for the ages of best actor and best supporting actor winners at an awards ceremony. the distributions of the ages are approximately bell-shaped. compare the z-scores for the actors in the following situation. best actor best supporting actor muequals42.0 muequals49.0 sigmaequals7.3 sigmaequals15 in a particular year, the best actor was 59 years old and the best supporting actor was 45 years old. determine the z-scores for each. best actor: z equals best supporting actor: z equals (round to two decimal places as needed.) interpret the z-scores. the best actor was (more than 2 standard deviations above more than 1 standard deviation above less than 1 standard deviation above less than 2 standard deviations below) the mean, which (is not, is) unusual. the best supporting actor was (less than 1 standard deviation below more than 1 standard deviation above more than 2 standard deviations below more than 1 standard deviation below) the mean, which (is is not) unusual.
