Answer:
$122.1
Step-by-step explanation:
We are given the following data in the question
$124, $256 , $118, $441, $122, $335, $340, $191
Step 1
Find the mean
Mean = Sum of Terms / Number of Terms
Number of Terms = 8
Mean = ($124 + $256 + $118 + $441 + $122 + $335 + $340 + $191 )/ 8
Mean = $1927/8
= $240.875
Approximately to 1 decimal place
$240.9
Step 2
Standard deviation formula
S = √( x - μ)²/ N - 1),
N = Number of terms
μ = Mean
S = √[($124 - $240.9)² + ($256 - $240.9)² + ($118 - $240.9)² + ($441 - $240.9)² + ($122 - $240.9)² + ($335 - $240.9)² + ($340 - $240.9)²+ ($191 -$240.9)²/ 8 - 1]
S = $122.0895
Approximately to 1 decimal place
S = $122.1
Therefore, the standard deviation for the given data is $122.1
Answer: Symmetric Property
Explanation: The symmetric property states that x = y, then y = x.
So the symmetric property allows us to
switch the left and right sides of an equation.
