Answer :
To solve the problem about Jada's granola bar sales, we'll calculate the mean, median, and mode of the sales data.
1. Find the mean number of granola bars Jada sold per day.
The mean (or average) is found by adding up all the numbers and then dividing by the number of numbers.
Jada's sales for each day are:
- Monday: 12
- Tuesday: 13
- Wednesday: 12
- Thursday: 18
- Friday: 9
- Saturday: 15
- Sunday: 12
First, add all the sales:
[tex]12 + 13 + 12 + 18 + 9 + 15 + 12 = 91[/tex]
Next, divide the total by the number of days (7):
[tex]\text{Mean} = \frac{91}{7} = 13[/tex]
So, the mean number of granola bars sold per day is 13.
2. Find the median number of granola bars sold.
The median is the middle number in a sorted list of numbers. First, sort the numbers:
9, 12, 12, 12, 13, 15, 18
Since there are 7 numbers, the median is the fourth number:
The median is 12.
3. Find the mode of the sales data.
The mode is the number that appears most frequently in the list.
Looking at the sales:
- 12 appears 3 times,
- 13 appears once,
- 18 appears once,
- 9 appears once,
- 15 appears once.
The number 12 appears the most frequently.
So, the mode is 12.
In summary:
- The mean number of granola bars sold per day is 13.
- The median number of granola bars sold is 12.
- The mode of the sales data is 12.
