True or False: The main principle behind the Pareto chart is the ability to separate the "vital few" from the "trivial many."

SCENARIO 2-8 The Stem-and-Leaf display represents the number of times in a year that a random sample of 100 "lifetime" members of a health club actually visited the facility. -Referring to Scenario 2-8, if a frequency distribution with equal sized classes was made from this data, and the first class was "0 but less than 10," the frequency of the fifth class would be ________.

SCENARIO 2-10 The histogram below represents scores achieved by 200 job applicants on a personality profile. -Referring to the histogram from Scenario 2-10, the number of job applicants who scored between 30 and below 60 is _______.

SCENARIO 2-5 The following are the duration in minutes of a sample of long-distance phone calls made within the continental United States reported by one long-distance carrier. -Referring to Scenario 2-5, what is the cumulative relative frequency for the percentage of calls That lasted under 20 minutes?

SCENARIO 2-1 An insurance company evaluates many numerical variables about a person before deciding on an appropriate rate for automobile insurance.A representative from a local insurance agency selected a random sample of insured drivers and recorded, X, the number of claims each made in the last 3 years, with the following results. -Referring to Scenario 2-1, how many drivers are represented in the sample?

SCENARIO 2-12 The table below contains the opinions of a sample of 200 people broken down by gender about the latest congressional plan to eliminate anti-trust exemptions for professional baseball. -Referring to Scenario 2-12, of those for the plan in the sample, ________ percent were females.

SCENARIO 2-8 The Stem-and-Leaf display represents the number of times in a year that a random sample of 100 "lifetime" members of a health club actually visited the facility. -Referring to Scenario 2-8, ________ of the 100 members visited the health club no more than 12 times in a year.

When comparing two or more large sets of numerical data, the distributions being developed should use the same ________.

SCENARIO 2-12 The table below contains the opinions of a sample of 200 people broken down by gender about the latest congressional plan to eliminate anti-trust exemptions for professional baseball. -Referring to Scenario 2-12, if the sample is a good representation of the population, we can expect _______ percent of the population will be for the plan.

SCENARIO 2-13 Given below is the stem-and-leaf display representing the amount of detergent used in gallons (with leaves in 10ths of gallons)in a day by 25 drive-through car wash operations in Phoenix. 2-36 Organizing and Visualizing Variables -Referring to Scenario 2-13, if a relative frequency or percentage distribution for the detergent data is constructed, using "9.0 but less than 10.0 gallons" as the first class, what percentage of drive-through car wash operations use at least 10 gallons but less than 13 gallons of detergent in a day?

SCENARIO 2-4 A survey was conducted to determine how people rated the quality of programming available on television.Respondents were asked to rate the overall quality from 0 (no quality at all)to 100 (extremely good quality).The stem-and-leaf display of the data is shown below. -Referring to Scenario 2-4, what percentage of the respondents rated overall television quality With a rating of 80 or above?

True or False: Apple Computer, Inc.collected information on the age of their customers. Suppose the youngest customer was 12 and the oldest was 72.To study the distribution of the age among its customers, it can use a percentage polygon.

True or False: The original data values cannot be determined once they are grouped into a frequency distribution table.
