Question

Prices for the salad bar at some local restaurants are $8.95, $6.50, $12.25, $9.90, $11.00, $8.95, $10.75, and $6.50.

Answer 1

Mean:9.35
Median: 9.42
Mode: 8.95 and 6.50

Answer 2

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.
