A telephone survey contacts a random sample of 1,000 LosAngeles telephone numbers, of which 58% are unlisted. In this example,A. 62% is a parameter, and 58% is a statistic.B. 58% is a parameter, and 62% is a statistic.C. 62% and 58% are both parameters.D. 58% and 62% are both statistics.E. The numbers 58% and 62% are neither statistics nor parameters.

Answer 1

A parameter is a number describing a whole population, while a statistic is a number describing a sample

So as we can see on the question

62% represent a whole population, "all residential phone numbers" so 62% is a parameter

while 58% is describing the sample of 1000 random telephone numbers

so 58% is a statistic

So the right answer is the A
