Question

find the (a) mean, (b) median, (c) mode, and (d) midrange for the data and then (e) answer the given questions. listed below are selling prices (dollars) of tvs that are 60 inches or larger and rated as a \best buy\ by a popular 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 central tendency? 1950 1100 1050 1100 1250 1200 1100 1860 1200 1500 1100 1750 d. find the midrange. the midrange is $ 1500. (type an integer or a decimal rounded to one decimal place as needed.) e. are the resulting statistics representative of the population of all tvs that are 60 inches and larger? choose the best answer below. a. the sample consists of the \best buy\ tvs, so it is not a random sample and is not likely to be representative of the population. b. since the sample is random and the sample size is greater than 10, the sample can be considered to be representative of the population. c. since the sample is random and the sample size is greater than 10, the sample should not be considered to be representative of the population. d. the sample consists of the \best buy\ tvs, so it is a random sample and is likely to be representative of the population.

Explanation:

Step1: Recall sample representativeness concept

A random sample is needed for representativeness. The given sample is of "best - buy" TVs.

Step2: Analyze the sample type

Since it's a sample of "best - buy" TVs, it's not a randomly selected sample from all 60 - inch and larger TVs.

Answer:

A. The sample consists of the "best buy" TVs, so it is not a random sample and is not likely to be representative of the population.
