Companion test bank for Business Statistics: A Decision-Making Approach, 10th Edition by David F. Groebner, Patrick W. Shannon, and Phillip C. Fry (Pearson, 2018). This comprehensive resource covers all 20 chapters and includes hundreds of exam-style questions—true/false, multiple-choice, short-answer, matching, and scenario-based items—with verified answers and detailed rationales . Content spans the full business statistics curriculum: the where, why, and how of data collection; graphs, charts, and tables for describing data; numerical measures; introduction to probability; discrete and continuous probability distributions (including normal, uniform, and exponential distributions); sampling distributions; estimating single population parameters; introduction to hypothesis testing; estimation and hypothesis testing for two population parameters; hypothesis tests for population variances; analysis of variance (ANOVA); goodness-of-fit tests and contingency analysis; linear regression and correlation analysis; multiple regression analysis and model building; analyzing and forecasting time-series data; introduction to nonparametric statistics; introducing business analytics; introduction to decision analysis; and introduction to quality and statistical process control . Key topics include standard normal distribution conversion (any normal distribution can be converted to a standard normal distribution), z-value probability comparisons, uniform distribution probability calculations, exponential distribution applications (time between arrivals), descriptive vs. inferential statistics, hypothesis testing for two independent populations with known standard deviations, binomial and Poisson distributions, control chart principles (x-bar chart based on normal distribution), and process variation (common cause vs. special cause) . Designed for undergraduate and graduate business statistics students, instructors, and professionals preparing for coursework and examinations. Edition Details: Authors: David F. Groebner, Patrick W.

,Chapter 6 Introduction to Continuous Probability Distributions



1) The normal distribution is one of the most frequently used discrete
probability distributions.
Answer: FALSE

Diff: 1
Keywords: normal distribution
Section: 6-1 The Normal Probability Distribution

Outcome: 1


2) Typically, a continuous random variable is one whose value is determined by
measurement instead of counting.

Answer: TRUE
Diff: 1

Keywords: continuous, random, variable

Section: 6-1 The Normal Probability Distribution

Outcome: 3


3) The number of defects manufactured by workers in a small engine plant is an
example of a discrete random variable.
Answer: TRUE

Diff: 1
Keywords: discrete, random, variable

Section: 6-1 The Normal Probability Distribution
Outcome: 3



4) One example of a difference between discrete random variables and continuous
random variables is that in a discrete distribution P(x >2)= P(x 2> 3) while in a
continuous distribution P(x > 2) is treated the same as P(x2> 2).

,Answer: TRUE
Diff: 2

Keywords: discrete, continuous, random, variable
Section: 6-1 The Normal Probability Distribution
Outcome: 3


5) The probability distribution for a continuous random variable is represented by a
probability density function that defines a curve.
Answer: TRUE
Diff: 1
Keywords: probability, density, continuous, variable
Section: 6-1 The Normal Probability Distribution
Outcome: 2


6) When graphed, the probability distribution for a discrete random variable looks
like a histogram.
Answer: TRUE
Diff: 2
Keywords: discrete, variable, distribution
Section: 6-1 The Normal Probability Distribution
Outcome: 3
7) For a continuous distribution the total area under the curve is equal to 100.
Answer: FALSE
Diff: 1
Keywords: normal, distribution, continuous, variable
Section: 6-1 The Normal Probability Distribution
Outcome: 3

, 8) A continuous random variable approaches normality as the level of skewness
increases.
Answer: FALSE
Diff: 2
Keywords: continuous, variable, random
Section: 6-1 The Normal Probability Distribution
Outcome: 3


9) If the mean, median and mode are all equal for a continuous random variable,
then the random variable is normally distributed.
Answer: FALSE
