Q:

# 1. Preliminaries Remember the setup: We (the RAF in World War II) want to know the number of warplanes fielded by the Germans. That number is N. The warplanes have serial numbers from 1 to N, so N is also equal to the largest serial number on any of the warplanes. We only see a small number of serial numbers (assumed to be a random sample with replacement from among all the serial numbers), so we have to use estimation. Question 1.1 Is N a population parameter or a statistic? If we compute a number using our random sample that's an estimate of N, is that a population parameter or a statistic?

Accepted Solution

A:
Answer:N is a population parameter; the computation using an estimate of N is a statistic.Step-by-step explanation:A parameter is a measure of a population.  The number of warplanes fielded total is N; this makes it the population.  Thus N is a parameter.A statistics is a measure of a sample.  The number computed using an estimate of N would be based on a sample, since it is an estimate of N; this makes it a statistic.
