STATISTICS 8 CHAPTERS 1 TO 6, SAMPLE MULTIPLE CHOICE QUESTIONS Correct answers are in bold This scenario applies to Questions 1 and 2: A study was done to compare the lung capacity of coal miners to the lung capacity of farm workers. The researcher studied 200 workers of each type. Other factors that might affect lung capacity are smoking habits and exercise habits. The smoking habits of the two worker types are similar, but the coal miners generally exercise less than the farm workers. 1. Which of the following is the explanatory variable in this study? a. Exercise b. Lung capacity c. Smoking or not d.

sample points. Examples are the sample mean ¯x = x i/n and the sample variance s2 = (x i − ¯x)2/n A random sample may be regarded as a microcosm of the population from which it is drawn. Therefore, we might attempt to estimate the moments of the population’s p.d.f f(x) by the corresponding moments of the sample statistics.
