Example Questions

Example Question #81 : Statistics And Probability

Consider the following set:

15,17,12,13,14,11,14,10,22,16,9

Find the mean of the set.

Possible Answers:

13.2

13.9

14.1

13.5

Correct answer:

13.9

Explanation:

To find the mean of a set of numbers, we add all of the numbers together and then divide by the number of numbers in the set:

15+17+12+13+14+14+11+10+22+16+9=153

$\frac{153}{11}=13.9$

From this we can find that the mean is 13.9

Example Question #82 : Statistics And Probability

What is the mean of , , , and ?

Possible Answers:

$\frac{25}{2}$

$\frac{19}{2}$

$\frac{21}{2}$

$\frac{27}{2}$

$\frac{23}{2}$

Correct answer:

$\frac{23}{2}$

Explanation:

In order to find the mean of a set of numbers, we divide the sum of the numbers by the amount of numbers in the set. Since we have numbers in the set, we can calculate the mean as the following:

$\frac{10+11+12+13}{4}$

$=\frac{21+25}{4}$

$=\frac{46}{4}$

$=\frac{23}{2}$

Example Question #83 : How To Find Mean

What is the mean of , , , , and ?

Possible Answers:

$\frac{8}{5}$

$\frac{6}{5}$

$-\frac{6}{5}$

$-\frac{8}{5}$

Correct answer:

$\frac{6}{5}$

Explanation:

In order to find the mean of a set of numbers, we divide the sum of the numbers by the amount of numbers in the set. Since we have numbers in the set, we can calculate the mean as the following:

$\frac{2+(-4)+6+(-8)+10}{5}$

$=\frac{(-4)+8+(-8)+10}{5}$

$=\frac{(-4)+10}{5}$

$=\frac{6}{5}$

Example Question #84 : How To Find Mean

What is the mean of , , , and ?

Possible Answers:

$\frac{1}{4}$

$\frac{1}2{}$

$-\frac{1}{4}$

$-\frac{1}{2}$

Correct answer:

$-\frac{1}{4}$

Explanation:

In order to find the mean of a set of numbers, we divide the sum of the numbers by the amount of numbers in the set. Since we have numbers in the set, we can calculate the mean as the following:

$\frac{1+(-1)+2+(-3)}{4}$

$=\frac{2+(-3)}{4}$

$=-\frac{1}{4}$

What is the mean of 5,4,3, and ?

Possible Answers:

$\frac{5}{2}$

$\frac{9}{2}$

$\frac{11}2{}$

$\frac{7}{2}$

$\frac{3}{2}$

Correct answer:

$\frac{7}{2}$

Explanation:

In order to find the mean of a set of numbers, we divide the sum of the numbers by the amount of numbers in the set. Since we have numbers in the set, we can calculate the mean as the following:

$\frac{5+4+3+2}{4}$

$=\frac{9+5}{4}$

$=\frac{14}{4}$

$=\frac{7}{2}$

Possible Answers:

Correct answer:

Explanation:

In order to find the mean of a set of numbers, we divide the sum of the numbers by the amount of numbers in the set. Since we have numbers in the set, we can calculate the mean as the following:

$\frac{6+(-3)+7+(-2)}{4}$

$=\frac{3+5}{4}$

$=\frac{8}{4}$

Possible Answers:

$\frac{4}{5}$

$\frac{1}{2}$

$\frac{2}{3}$

$\frac{3}{5}$

Correct answer:

$\frac{2}{3}$

Explanation:

In order to find the mean of a set of numbers, we divide the sum of the numbers by the amount of numbers in the set. Since we have numbers in the set, we can calculate the mean as the following:

$\frac{1+(-1)+2}{3}$

$=\frac{2}{3}$

Possible Answers:

Correct answer:

Explanation:

In order to find the mean of a set of numbers, we divide the sum of the numbers by the amount of numbers in the set. Since we have numbers in the set, we can calculate the mean as the following:

$\frac{2+(-4)+6+8}{4}$

$=\frac{14-2}{4}$

$=\frac{12}{4}$

$\frac{17}{2}$

$\frac{19}{2}$

$\frac{25}{2}$

$\frac{21}{2}$

Correct answer:

$\frac{17}{2}$

Explanation:

In order to find the mean of a set of numbers, we divide the sum of the numbers by the amount of numbers in the set. Since we have numbers in the set, we can calculate the mean as the following:

$\frac{10+9+8+7}{4}$

$=\frac{34}{4}$

$=\frac{17}{2}$

Example Question #87 : How To Find Mean

What is the mean of $\frac{1}{2},\frac{1}{4}$ and $\frac{1}{3}$ ?

Possible Answers:

$\frac{4}{13}$

$\frac{13}{36}$

Does Not Exist

$-\frac{4}{13}$

$-\frac{13}{4}$

Correct answer:

$\frac{13}{36}$

Explanation:

In order to find the mean of a set of numbers, we divide the sum of the numbers by the amount of numbers in the set. Since we have numbers in the set, we can calculate the mean as the following:

$\frac{\frac{1}{2}+\frac{1}{4}+\frac{1}{3}}{3}$

$=\frac{\frac{6}{12}+\frac{3}{12}+\frac{4}{12}}{3}$

$=\frac{\frac{13}{12}}{3}$

$=\frac{13}{12}\times\frac{1}{3}$

$=\frac{13}{36}$
