colin kept track of how many boxes of cookies he sold over the past 7 days. boxes of cookies sold what is the mean of the numbers?
Answer
Explanation:
Step1: Identify the data values
The number of boxes sold each day are 60, 20, 90, 0, 70, 0, 40.
Step2: Calculate the sum of data values
$60 + 20+90 + 0+70+0 + 40=280$
Step3: Determine the number of data - points
There are 7 days, so $n = 7$.
Step4: Calculate the mean
The mean $\bar{x}=\frac{\text{Sum of data values}}{\text{Number of data - points}}=\frac{280}{7}=40$
Answer:
40
