- The mean of the number of hours worked by these students is 14 hours.
- The median is 12.5 hours.
The mean is the sum of all the hours listed divided by the number of seniors asked:
= ( 0 + 0 + 0 + 8 + 8 + 10 + 12 + 13 + 15 + 15 + 17 + 20 + 22 + 56) / 14
= 196 / 14
= 14 hours
The mean number of hours is 14 hours.
The median
Because the number of student interviewed is an even number, the median is calculated by taking the average of the two numbers in the middle.
<em>The numbers are ⇒ 12, 13</em>
Median is therefore :
= ( 12 + 13) /2
= 12.5 hours
In conclusion, the mean is 14 hours and the median is 12.5 hours.

Answer:
Results are below.
Step-by-step explanation:
Giving the following information:
The original amount of money on the gift card was $45. After buying 8 cups of coffee, the remaining balance was $25.
<u>First, we need to calculate the unitary value of each cup of coffee:</u>
Unitary cost= 20/8= $2.5
<u>Now, we can structure the remaining balance formula (A):</u>
A= 45 - 2.5x
x= cup of coffee
<u>After 2 cups:</u>
A= 45 - 2.5*2
A= 40
