During each episode, he produced a complete painting while teaching viewers how they could produce a similar painting. Ross completed 30 , 000 paintings in his lifetime. Although it was an art instruction show, PBS estimated that only 10 % of viewers painted along with Ross during his show based on surveys of viewers. For each of the following, also identify the population and explain your choice. a. Is the number 30 , 000 a parameter or a statistic? b. Is the number 10 % a parameter or a statistic?
