A company advertised that, on the average, 96% of their customers reported "very high satisfaction" with their services. The actual percentages reported in 15 samples were the following:
96, 96, 92, 35, 74, 96, 92, 74, 96, 96, 35, 92, 92, 96, 35
a. Find the mean, median, mode and midrange. b. Which measure of central tendency was given in the advertisement? c. Which measure of central tendency is the best indicator of the "average" in this situation?
