For 50 points the data set shows fuel efficiencies, in miles per gallon, of the vehicles featured in a car buying guide. 25 35 43 29 19 25 37 38 20 15 28 30 a. what is the five number summary of the data set? b. what is the range of the data set? (show your work) c. what is the iqr of the data set? (show your work)

Put the numbers in order from smallest to largest:

15, 19, 20, 25, 25, 28, 29, 30, 35, 37, 38, 43

Part A:

minimum = 15

maximum = 43

Q1 = (25+20) /2 = 45/2 =22.5

Q2= (28+29) /2 = 57/2 = 28.5

Q3 = (35+37)/2 = 72/2 = 36

Part B:  Range = Maximum - minimum = 43-15 = 28

C: IQR = Q3 - Q1 = 36 - 22.5 = 13.5

341

step-by-step explanation:

all you have to do is 9x31 (which equals 279) and then 20x31 (which equals 620). then you have to subtract. 620-279=341.

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.
