Which of the following is the graphical analog of a frequency table?

The mode is best described as the

Boxplots are most useful for.

Which measure of central location is meaningful when the data are categorical?

Which of the following statements are false?

The total frequency of the data whose ogive is shown below is approximately

Given the following boxplot where m is the median value, what statement could be made about the distribution of the data?

A time series plot is essentially a:

For a boxplot, the box itself represents what percent of the observations?

A histogram that has a single peak and looks approximately the same to the left and right of the peak is called:

If a variable has possible values –2, 6, and 17, then this variable is

A variable is classified as ordinal if:

Accepted characters: numbers, decimal point markers (period or comma), sign indicators (-), spaces (e.g., as thousands separator, 5 000), “E” or “e” (used in scientific notation). NOTE: For scientific notation, a period MUST be used as the decimal point marker.
Complex numbers should be in the form (a + bi) where “a” and “b” need to have explicitly stated values.
For example: {1+1i} is valid whereas {1+i} is not. {0+9i} is valid whereas {9i} is not.

A sample of 150 students at a State University was taken after the final business statistics exam to ask them whether they went partying the weekend before the final or spent the weekend studying, and whether they did well or poorly on the final. The following table contains the result.

If the sample is a good representation of the population, what percentage of those who did poorly on the final exam should we expect to have spent the weekend studying?  Place your answer in the blank, rounded to 2 decimal places. Do not use a percentage sign (%). For example, 44.44 would be a legitmate answer.

The histogram below represents scores achieved by 250 job applicants on a personality profile.

How many job applicants scored above 50? Place your answer in the blank. Do not use any stray symbols. For example, 123 would be a legitimate answer.

The following data represent the number of children in a sample of 10 families from Chicago: 4, 2, 1, 1, 5, 3, 0, 1, 0, and 2.

Compute the variance of the data. Place your answer, rounded to two decimal places, in the blank. For example, 3.45 would be a legitimate entry.

The histogram below represents scores achieved by 250 job applicants on a personality profile.

Sixty percent of the job applicants scored below what value?  Place your answer in the blank. Do not use any stray symbols. For example, 123 would be a legitimate answer.

The following data are the base salaries, in thousands of dollars, of 50 chief executive officers for a sample of companies doing business with the state of Connecticut. That is, the first entry in the table below corresponds to a salary of $125,000. A copy of this data set can be found in the Excel Workbook called CEOSalaries.xls.

Find the mean of the CEO salaries, in thousands of dollars, rounded to 2 decimal places. Do not use a dollar sign. Note: $177,760 should be recorded as 177.76.
