a cell phone company conducted a survey to determine if customers were satisfied with their cell phone service. the survey sample consisted of all customers who had contacted the company within the past year and who agreed to participate. of the 420 customers surveyed, 65% reported that they were not satisfied with their service. which statement about this sample is true? exactly 65% of all customers are not satisfied with the cell phone service. the sample includes all customers who made complaints to the company within the last year, and therefore is representative of the population. the sample might not be representative of the population because, in general, satisfied customers have no reason to contact the company. no generalizations can be made from this sample because the sample size is too small.

Answer

# Brief Explanations: The sample consists of customers who contacted the company in the past - year and agreed to participate. Satisfied customers are less likely to contact the company, so this sample may over - represent dissatisfied customers and not be representative of all customers. A sample size of 420 is not necessarily too small. Just because the sample has customers who made complaints doesn't mean it's representative as it excludes satisfied non - complainers. And we can't say exactly 65% of all customers are not satisfied based on this non - representative sample. # Answer: The sample might not be representative of the population because, in general, satisfied customers have no reason to contact the company.
