1. The Department of Education wishes to estimate the proportion of all col- lege students who have
a job off-campus. It surveyed 1600 randomly selected students; 451 had such jobs. The population of
interest to the Department of Education is:: All college students.
2. How would you find the mean of data from cells B1 to B10 in Excel?: = AVERAGE(B1:B10)
3. Using Excel, how would you find the standard deviation for a sample of data located in cells A1 to
A10 ?: = STDEV.S(A1:A10)
4. The standard deviation of a data set measures the of the
dataset.: variability
5. The score made by a particular student on a national standardized exam is the 75th percentile.
This means that: About 75% of all scores on the exam were equal to or less than his.
6. There were 1000 students who took part in the common final exam on STAT 1222. The average is
70 with a standard deviation 8. If a student got a z-score of
3.10 in this exam, which of the following is true?: Compared with other students in this exam, this
student did extremely well.
7. The mean score on a standardized math exam is 75; the standard deviation is 8. Zack is told that
the z-score of his exam score is -1.25.
Which of the following statements is true?: Zack's score is below the class average.
8. Population: A collection of persons, things, or objects under study
9. Parameter: Any numerical characteristic of the entire population
10.Sample: a subset of the population

(e.g. number of people in a room)
17.Quantitative Continuous: Any number in a range (fraction, decimal, irrational), generally can
be measured
(e.g. how tall is each person in a room)
