Question

a variety of two types of snack packs are delivered to a store. the box plots compare the number of calories in each snack pack of trail mix and in each snack pack of crackers. which statement is true about the box plots? the interquartile range of the trail mix data is greater than the range of the cracker data. the value 70 is an outlier in the trail mix data. the upper quartile of the trail mix data is equal to the maximum value of the cracker data. the number of calories in the packs of trail mix have a greater variation than the number of calories in the packs of crackers.

Explanation:

Step1: Recall range formula

Range = Maximum - Minimum.

Step2: Find range of trail - mix data

For trail - mix, minimum is 70 and maximum is 115. Range of trail - mix = 115 - 70=45.

Step3: Find range of cracker data

For crackers, minimum is 75 and maximum is 85. Range of crackers = 85 - 75 = 10.

Step4: Compare ranges

Since 45>10, the range of the trail - mix data is greater than the range of the cracker data.

Answer:

The interquartile range of the trail mix data is greater than the range of the cracker data.
