Answer: mean = $9.35 median= 9.375 mode =8.95
Step-by-step explanation:
To find the mean of the set of datas in the question
mean = sum of all the datas / no. of datas
mean = $8.95+$6.50+$12.25+$9.90+$11.00+$8.95+$10.75+$6.50 / 8
=$74.8/8 = $9.35
Median
To get the median,we re-arrange from lowest to highest and then pick the middle number
$6.50, $6.50, $8.95, $8.95, $9.90, $10.75, $11.00, $12.25
We have two middle numbers, which are $8.95 and $9.90
since there are two middle numbers, we add them and then divide by 2
median = $8.95 + $9.90 / 2
=$18.85/2
=$9.425
mode is the number with the highest frequency
$6.50 appears twice, so also $8.95
They are the two modes.
