Critical Thinking. For Exercises 5-20, watch out for these little buggers. Each of these exercises involves some feature that is somewhat tricky. Find the (a)
11. TV Prices Listed below are selling prices (dollars) of TVs that are 60 inches or larger and rated as a “best buy” by Consumer Reports magazine. Are the resulting statistics representative of the population of all TVs that are 60 inches and larger? If you decide to buy one of these TVs, what statistic is most relevant, other than the measures of
