Step-by-step explanation:
First we must calculate the interquartile range (IQR), using this equation:
Based on the information provided we fill in:
In order to find what the range for the data set is we need to use the Interquartile Rule:
× 
×
× 
Now we plugin in:
Any number below 25.5 is a possible outlier and any number above 77.5 is a possible outlier.
Answer:
Based on the results of the calculations, 25 could be a possible outlier in the data set.
Answer:
They ran a total of 4 miles
Step-by-step explanation:
2 1/3 + 1 2/3 = 4
Answer:
Since while finding a percent change i.e. to find the percent increase or decrease in the quantity the old value or we can say the original value plays a vital role.
<em>" Because Percentage Change is all about comparing old to new values "</em>
If we do not know the original value then there is no means of comparing the new quantity, the new quantity is to be measured with respect to the old quantity.Hence, the original quantity is to be kept in the denominator.
1) First: work out the difference (increase) between the two numbers you are comparing.
2) Increase = New Number - Original Number.
3) Then: divide the increase by the original number and multiply the answer by 100.
4) % increase = Increase ÷ Original Number × 100.
