Complete Question

Consider the speed in miles per hour that Officer Williams clocked the last seven drivers at with his radar. Find the interquartile range of the speeds.

Speeds of the drivers in miles per hour is given as:

a) 58 miles/hour

b) 72 miles/hour

c) 55 miles/hour

d) 65 miles/hour

e) 70 miles/hour

f) 81 miles/hour

g) 66 miles/hour

Answer:

66 miles per hour

Step-by-step explanation:

Inter quartile range can be defined as the measurement in statistics that indicates the middle of a set of given data when you separate that data into two equal quartiles, one quartile on the left and one quartile on the right leaving a specific figure or number in the center.

It is important to note that the given set of data must be rearranged in ascending order or rank from the least to the greatest before finding the inter quartile range.

The speed of the last seven drivers on Officer Williams radar was given as:

a) 58 miles/hour

b) 72 miles/hour

c) 55 miles/hour

d) 65 miles/hour

e) 70 miles/hour

f) 81 miles/hour

g) 66 miles/hour

This speeds would be re arranged properly as :

55, 58, 65, 66, 70, 72, 81

The inter quartile range of these speeds is the number in the middle and that is 66 miles per hour.
