The response is qualitative because the number of people satisfied can be counted. D. The response is quantitative because the number of people satisfied can be counted. (b) Explain why the sample proportion, p, is a random variable. What is the source of the variability? A. The sample proportion is a random variable because the value of varies from sample to sample. The variability is due to the fact that different people feel differently regarding their satisfaction OB. The sample proportion p is a random variable because the value of p represents a random person included in the sample. The variability is due to the fact that different people feel differently regarding their satisfaction. OC. The sample proportion p is a random variable because the value of p varies from sample to sample. The variability is due to the fact that people may not be responding to the question truthfully D. The sample proportion p is a random variable because the value of p represents a random person included in the sample.
