Now, convert each fraction to be out of twelfths. Do this by setting up a proportion. 2/3 = x/12. Cross multiply and divide. 2*12 = 24. 24/3 = 8. Therefore, 2/3 = 8/12.

Do the same for 1/4. 1/4 = x/12. Cross multiply and divide. 12*1 = 12. 12/4 = 3. Therefore, 1/4 = 3/12.

Now add these two fractions by adding the numerators and keeping the denominators the same. 8/12 + 3/12 = 11/12.

Subtract this answer from 1 (12/12). 12/12 - 11/12 = 1/12

The data set below represents the total number of home runs that a baseball player hit each season for 11 seasons of play. What

goblinko [34]

Answer:

The interquartile range of the data is 12

Step-by-step explanation:

Data : 14, 22, 19, 21, 30, 32, 25, 15, 16, 27, 28 12 16 22 28

Data in ascending order : 12 ,14 ,15 ,16 ,16 ,19 ,21 ,22 ,22 ,25 ,27 ,28 ,28 ,30 ,32

Lower quartile :12 ,14 ,15 ,16 ,16 ,19 ,21

Q1 is the median of lower quartile

n = 7

Median = $\frac{n+1}{2} \text{th term}=\frac{7+1}{2}=4 \text{th term}$ =16

Upper quartile :22 ,25 ,27 ,28 ,28 ,30 ,32

Q3 is the median of upper quartile

n = 7

Median = $\frac{n+1}{2} \text{th term}=\frac{7+1}{2}=4 \text{th term}$ =28

IQR = Q3-Q1=28-16= 12

Hence the interquartile range of the data is 12
