Chapter 2: Q 33. (page 109)

Jorge鈥檚 score on Exam 1in his statistics class was at the 64th percentile of the scores for all students. His score falls

(a) between the minimum and the first quartile.

(b) between the first quartile and the median.

(c) between the median and the third quartile.

(d) between the third quartile and the maximum.

(e) at the mean score for all students.

Short Answer

Expert verified

The correct option is (c).

Step by step solution

01

Step 1. Given

J鈥檚 score on Exam 1in his statistics class was at the64th percentile of the scores for all students.

02

Step 2. Concept

The pth percentile of a distribution is the value with p% of the observations less than it.

03

Step 3. Explanation

The 25th percentile is represented by the first quartile, the median by the 50th percentile, and the 75th percentile by the third quartile. J's score was in the 64th percentile. Between the median (50th percentile) and the third quartile is this (75th percentile). Therefore, Option (c) is the best answer.

Teacher raises A school system employs teachers at salaries between \(28,000 and \)60,000. The teachers鈥� union and the school board are negotiating the form of next year鈥檚 increase in the salary schedule.

(a) If every teacher is given a flat \(1000 raise, what will this do to the mean salary? To the median salary? Explain your answers.

(b) What would a flat\)1000 raise do to the extremes and quartiles of the salary distribution? To the standard deviation of teachers鈥� salaries? Explain your answers.

Normal is only approximate: ACT scores Scores on the ACT test for the 2007 high school graduating class had mean 21.2and standard deviation 5.0. In all, 1,300,599students in this class took the test. Of these, 149,164had scores higher than 27and another 50,310had scores exactly 27. ACT scores are always whole numbers. The exactly Normal N(21.2,5.0)distribution can include any value, not just whole numbers. What鈥檚 more, there is no area exactly above 27under the smooth Normal curve. So ACT scores can be only approximately Normal. To illustrate this fact, find

(a) the percent of 2007ACT scores greater than 27.

(b) the percent of 2007ACT scores greater than or equal to 27.

(c) the percent of observations from theN(21.2,5.0) distribution that are greater than 27. (The percent greater than or equal to 27 is the same, because there is no area exactly over 27.)
