Question

an insurance company crashed four cars in succession at 5 miles per hour. the cost of repair for each of the four crashes was $419, $454, $409, $238. compute the range, sample variance, and sample standard deviation cost of repair.

the range is $216.
$s^{2} = 9334$ dollars$^{2}$
(round to the nearest whole number as needed.)
$s = $□
(round to two decimal places as needed.)

Explanation:

Step1: Identify sample variance

Given $s^2 = 9334$

Step2: Calculate standard deviation

Take square root of variance:
$s = \sqrt{9334}$

Step3: Round to two decimals

Compute and round the result

Answer:

$96.61$
