Question

A car's velocity, in mph, is recorded simultaneously by five different sensors, with the results: 45, 46, 46, 45, 48. Estimate a range of values in which the car's true velocity is likely to lie.

Answer 1

Answer:
`45-48\ \text{mph}`

Explanation:

Given

Car velocity is given by
`45, 46, 46, 45, 48`

The range of a given set of data is given by

`\text{Range=Max-min. value}`

Maximum velocity=48

Minimum velocity=45

The Range of velocity is

`\Rightarrow 48-45=3`

Velocity lies between
`45-48\ \text{mph}`
