Example Question #177 : Statistics And Probability

Find the mean of the following data set:

33, 7, 22, 1, 29, 8, 13, 7

Possible Answers:

Correct answer:

Explanation:

To find the mean of a data set, we use the following formula:

$\text{mean} = \frac{\text{sum of numbers}}{\text{quantity of numbers}}$

Given the data set, we know

$\text{mean} = \frac{33+7+22+1+29+8+13+7}{8}$

$\text{mean} = \frac{120}{8}$

$\text{mean} = 15$

Example Question #172 : Statistics And Probability

Find the mean of the dataset: [5,8,10,3,26]

Possible Answers:

$\textup{No mean.}$

$\frac{52}{5}$

$\frac{62}{5}$

$\frac{42}{5}$

Correct answer:

$\frac{52}{5}$

Explanation:

The mean is the average of all the numbers given in the dataset.

Add all the integers given in the dataset.

5+8+10+3+26 = 52

Divide this number by the total numbers in the dataset.

The answer is: $\frac{52}{5}$

Example Question #1601 : Algebra 1

Determine the mean for the following dataset: [2,9,6,3,8]

Possible Answers:

$\frac{28}{5}$

$\frac{29}{5}$

$\frac{38}{5}$

Correct answer:

$\frac{28}{5}$

Explanation:

The mean is the average of all the numbers in the dataset.

Add all the numbers.

2+9+6+3+8+= 28

Divide this number by the total amount of numbers in the dataset.

The answer is: $\frac{28}{5}$

Example Question #180 : Statistics And Probability

A test was given to a class of students. The average for the class was .Two students scored 100 , two scored , two scored and two scored . For the remaining two students, one scored twice as much as the other. How much did the two remaining students score?

Possible Answers:

40,80

37.5,75

50,100

45,90

43,86

Correct answer:

40,80

Explanation:

It is clear that among the remaining two students, one scored lower than the other. Let the lower score of the remaining student be . Then the higher of the two scores is (as is twice as much as ). We want to find the values for and .

The sum of scores for the students is 630 . We know that average score (Here ) is sum of all the scores (Here 630+x+2x = 630+3x )divided by the total number of scores (Here ).

$\frac{630+3x}{10}=75$

630+3x=750

3x=750-630=120

$x=\frac{120}{3}=40$

2x= 2(40)=80

Example Question #181 : Statistics And Probability

A test was given to a class of students. The average for the class was .Three students scored 100 , two scored , two scored and two scored . What was the score for the remaining one student?

Possible Answers:

Correct answer:

Explanation:

Let the score of the remaining student be .The sum of scores for the nine students is 730 . We know that average score (Here ) is sum of all the scores (Here (730+x) )divided by the total number of scores (Here ). Therefore,

$\frac{730+x}{10}=80$

730+x=800

x=800-730=70

Therefore the remaining one student scored .

Example Question #182 : Statistics And Probability

A test was given to a class of students. Three students scored 100 , two scored , one scored , two scored and two scored . What was the average score of the class?

Possible Answers:

81.2

Correct answer:

81.2

Explanation:

The average is the sum of all the scores divided by the total number of scores.

Here the sum of all the scores is

100+100+100+90+90+82+75+75+50+50 =812 .

There are students, therefore scores.

$\frac{812}{10}=81.2$

Example Question #182 : Statistics And Probability

In the following data set that has been arranged in ascending order:

1, 2, 5, x, 10, 15, y, 22, z

The mean is twice the median. Find the mean.

Possible Answers:

Not enough information is given.

Correct answer:

Explanation:

Here if we started to calculate mean by its definition we would get into trouble because we don't know what x,y,z are.

However, we are given that the data set is arranged. Since there are odd number of terms (i.e ), we know that $(\frac{9+1}{2})^{th}$ term is the median.

This is the $5^{th}$ term i.e .

Hence the mean is

2(10)=20

Example Question #183 : Statistics And Probability

Find the mean of the dataset: [-2.3,2.4,-2.5]

Possible Answers:

0.866

0.733

-0.733

-0.8

0.8

Correct answer:

-0.8

Explanation:

Add the numbers provided.

-2.3+2.4-2.5= -2.4

Divide this number by the total numbers in the dataset.

$\frac{-2.4}{3} = -0.8$

The average is: -0.8

Example Question #184 : Statistics And Probability

Find the mean: [-2,-9,-6,-8,0,0,1]

Possible Answers:

$-\frac{24}{5}$

$-\frac{24}{7}$

$-\frac{25}{7}$

Correct answer:

$-\frac{24}{7}$

Explanation:

Add all the numbers in the set.

-2+(-9)+(-6)+(-8)+0+0+1=-24

There are a total of seven numbers.

The mean is the average of the dataset. Divide negative by .

The answer is: $-\frac{24}{7}$
