Mean Versus Median 1) Sarah and Andrew were comparing prices of their favorite energy bar. Eight grocery stores
sell the PR energy bar for the following prices:
$1.09 $1.29 $1.29 $1.35 $1.39 $1.49 $1.59 $1.79
Sarah claims the average price of the candy bar is $1 37 but Andrew disagreed and said the
average price of the energy bar is actually $1.41. How did Sarah and Andrew come up with these
prices? Based on their calculations, who do you think is correct and why?

Kindly check explanation

Step-by-step explanation:

Given the data:

$1.09 $1.29 $1.29 $1.35 $1.39 $1.49 $1.59 $1.79

Average value :

Sarah = $1.37

Andrew = $1.41

Obtaining the median:

(n + 1) / 2

n = number of observations = 8

(8 + 1) / 2 = 9 /2 = 4.5th observation

(4th +. 5th observations) / 2

(1.35 + 1.39) / 2 = $1.37

Finding the mean:

($1.09 + $1.29 + $1.29 + $1.35 + $1.39 + $1.49 + $1.59 + $1.79) /8

$11.28 / 8

= $1.41

Hence, the actual. Average value is the mean value of the data.

The median only gives the value at the middle of the distribution and not the average.

the least value out of the data shown is 5, maybe if you post a picture with it i could a little more.
