Of those students who are majoring in business, what percentage plans to go to graduate school? Their sales records are shown below: Number of Laptops Sold 0 - 19 20 - 39 40 - 59 60 - 79 80 - The class width of the above distribution is a.

If one develops a cumulative frequency distribution for the above data, the last class will have a frequency of a. The percentage of days in which the company sold at least 40 laptops is a. The number of days in which the company sold less than 60 laptops is a. Thirty students in the School of Business were asked what their majors were. Construct a frequency distribution and a bar chart. Construct a relative frequency distribution and a pie chart. Twenty employees of the Ahmadi Corporation were asked if they liked or disliked the new district manager.

Below you are given their responses. Let L represent liked and D represent disliked. Forty shoppers were asked if they preferred the weight of a can of soup to be 6 ounces, 8 ounces, or 10 ounces.

Construct a frequency distribution and graphically represent the frequency distribution. Construct a relative frequency distribution and graphically represent the relative frequency distribution.

A student has completed 20 courses in the School of Arts and Sciences. Her grades in the 20 courses are shown below. Develop a frequency distribution and a bar chart for her grades. Develop a relative frequency distribution for her grades and construct a pie chart. Construct a frequency distribution for this data. Let the first class be 50 - 59 and draw a histogram. Construct a cumulative frequency distribution. Construct a relative frequency distribution. Construct a cumulative relative frequency distribution.

The frequency distribution below was constructed from data collected from a group of 25 students. The frequency distribution below was constructed from data collected on the quarts of soft drinks consumed per week by 20 students. Construct a frequency distribution. Let the first class be 60 - There are students in the School of Business Administration.

The following shows the number of students in each major. In fact, for these data compact cars had the lowest fuel efficiencies. Higher fuel efficiencies are associated with front wheel drive cars.

Rear wheel drive cars had somewhat lower fuel efficiencies than four wheel drive cars. Higher fuel efficiencies are associated with smaller displacement engines and lower fuel efficiencies are associated with larger displacement engines. The scatter diagram shows that lower fuel efficiencies are associated with larger displacement engines.

Frequency distribution and percent frequency distribution of sales by division. This is considered General Motors most important division. General Motors would be almost certain to maintain these two divisions. At the time it was doubtful than General Motors would be able to maintain all three of the other divisions. The most frequent range is 3. General Electric had an unusually high dividend yield of 9.

The average SAT score looks to be a little over Scores below or above are unusual. Florida and California have been the states with the most Super Bowls. The most frequent winning points have been 0 to 4 points and 15 to 19 points. Both occurred in 10 Super Bowls.

The closest games was the 25th Super Bowl with a 1 point margin. It was played in Florida. The largest margin of victory occurred one year earlier in the 24 th Super Bowl. It had a 45 point margin and was played in Louisiana. More detailed information not available from the text information. This data set can be used in Chapter 2 and Chapter 3 to provide interesting data summaries about the points scored by the winning team and the points scored by the losing team in the Super Bowl.

For example, using the median scores, the median Super Bowl score was 28 to Population 0. The largest state is California The most frequent range for temperature was in the 60s 9 of Only one low temperature was above High temperatures were mostly 41 to 68, while low temperatures were mostly 21 to Low was 11; High was There is a positive relationship between high temperature and low temperature for these cities.

As one goes up so does the other. The results show support for a higher tax. Note that Converting the entries in the crosstabulation into column percentages provides the following results: Country Support. But the support for the higher tax is greater in the European countries. Germany is close in views to the United States with United States shows the lowest level of support for the higher tax with The batting averages for the junior and senior years for each player are as follows: Junior year: Allison Fealey Emily Janson.

Because Allison Fealey had the higher batting average in both her junior year and senior year, Allison Fealey should receive the scholarship offer. The combined or aggregated two-year crosstabulation is as follows: Combined 2-Year Batting Outcome.

Because Emily Janson has the higher batting average over the combined junior and senior years, Emily Janson should receive the scholarship offer.

The recommendations in parts a and b are not consistent. It shows that in interpreting the results based upon separate or un-aggregated crosstabulations, the conclusion can be reversed when the crosstabulations are grouped or aggregated. The authors clearly demonstrate how statistical results provide insights into business decisions and present solutions to contemporary business problems.

New cases and more than real business examples and memorable exercises, of which are new in this edition, present the latest statistical data and business information. With this book s comprehensive coverage and unwavering accuracy, you the topics best for your course, including thorough coverage of the latest statistical and business software. Up-to-date coverage of minitab 15 and excel , along with stat tools and other leading excel statistical add-ins within chapter appendices, provides ultimate.
