In a bar chart, the heights of the bars represent the frequencies in each class. A) True B) False The interquartile range is graphically presented in a A) Dot plot. B) Stem-and-leaf display. C) Box plot. D) Contingency table. Outliers are clearly presented in a A) Dot plot. B) Stem-and-leaf display. C) Box plot. D) Contingency table. A new car was put into production. It involved many assembly tasks. Each car was inspected at the end of the assembly line and the number of defects per unit was recorded. For the first 100 cars produced, there were 40 defective cars. Some of the cars had no defects; a few had one defect, and so on. The distribution of defects followed a Poisson distribution. Based on the first 100 produced, about how many out of every 1,000 cars assembled should have one or more defects? A) About 660 B) About 165 C) About 630 D) About 330 The Central Limit Theorem states that if the sample size, n, is sufficiently large, the sampling distribution of the means will be approximately normal, even when the population is skewed or uniform. A) True B) False Based on the central limit theorem, the sample mean can be used as a good estimator of the population mean, assuming that the size of the sample is sufficiently large. A) True B) False In multiple regression analysis, how is the degree of association between a set of independent variables and a dependent variable measured? A) Confidence intervals. B) Autocorrelation. C) Coefficient of multiple determination. D) Standard error of estimate.
