Pls
find the range and interquartile range of the data below.
13, 14, 15, 18, 19, 19, 19, 20
question 2 options:
range = 7
iqr = 5
range = 20
iqr = 4
range = 7
iqr = 4.5
range = 13 to 20
iqr = 14.5 to 19

Option c. Range = 7 IQR = 4.5

Step-by-step explanation:

We have to find the range and interquartile range of the data below :

13, 14, 15, 18, 19, 19, 19, 20

Range: The range of set of data is the difference between the highest and the lowest values of the data set.

Range = Highest value - lowest value

Range = 20 - 13 = 7

Interquartile range (IQR): To find the IQR first we find the median of the data set.

13, 14, 15, 18, 19, 19, 19, 20

Median = (18 + 19)/2 = 18.5

= 18.5

Now we calculate the median of first half of the data set to find

13, 14, 15, 18

= (14 + 15)/2 = 14.5

and then calculate the median of second half of the data set to find

19, 19, 19, 20

= (19 + 19)/2 = 19

IQR = -

IQR = 19 - 14.5 = 4.5

Range = 7

IQR = 4.5

hey there!

if she's saving for six months, let's divide the total number we need for the trip by six, dividing it into the amount that needs to be saved for each month.

500 ÷ 6 =

she needs to save at least this amount each month, so we should use this symbol: ≥

let x be the amount she saves each month.

your final answer is x ≥

hope this !
