a tennis fan counted the number of matches won by his favorite players last summer. tennis matches won last summer what is the mean of the numbers?
Answer
Explanation:
Step1: Count the number of data - points
There are 2 + 4+1+1+1+2 = 11 data - points.
Step2: Calculate the sum of the data - points
(0×2)+(1×4)+(2×1)+(3×1)+(4×1)+(6×2)=0 + 4+2 + 3+4+12 = 25.
Step3: Calculate the mean
The mean $\bar{x}=\frac{\text{Sum of data - points}}{\text{Number of data - points}}=\frac{25}{11}\approx2.27$.
Answer:
$\frac{25}{11}\approx2.27$
