a pasta company asked people about how much macaroni and cheese they ate. eating macaroni and cheese last month what is the mean of the numbers?
Answer
Explanation:
Step1: Count the number of data - points for each value
For 0: 3 data - points. For 1: 1 data - point. For 2: 1 data - point. For 3: 1 data - point. For 4: 1 data - point. For 5: 4 data - points. For 6: 1 data - point.
Step2: Calculate the sum of the products of each value and its frequency
$(0\times3)+(1\times1)+(2\times1)+(3\times1)+(4\times1)+(5\times4)+(6\times1)=0 + 1+2 + 3+4+20+6=36$.
Step3: Calculate the total number of data - points
$3 + 1+1+1+1+4+1=12$.
Step4: Calculate the mean
The mean $\bar{x}=\frac{36}{12}=3$.
