As a market researcher, compare the potential markets for sushi pizza.
ANSWER:
Solution :
Step 1 of 1:
Our goal is :
We need to find compare the potential markets for sushi pizza.
Given 10 randomly selected young adults.
So n=10.
Consider the data is
34, 39, 40, 46, 33, 31, 34, 14, 15, 45.
Now we have to calculate range.
First we have to arrange in ascending order.
14, 15, 31, 33, 34, 34, 39, 40, 45, 46.
Here the maximum value = 46 and the minimum value = 14.
The range formula is
Range = Maximum value-Minimum value
Range = 46-14
Range = 32
Therefore, the range is 32.
First we have to arrange in ascending order.
14, 15, 31, 33, 34, 34, 39, 40, 45, 46.
Then we take the 2 middle 34 and 34 values.
Now we have to add the 2 values and divide by 2.
Median =
Median =
Median = 34
Therefore, the median is 34.
Now we have to find the mean.
The mean formula is
Mean (
