an archer recalled how many times he hit the bulls - eye in the past 7 days. what is the mean of the numbers?

Explanation:

Step1: Identify the data values

From the bar - chart, the number of bull's - eyes on Tuesday is 4, on Wednesday is 8, on Thursday is 1, on Friday is 3, on Saturday is 8, on Sunday is 4, and on Monday is 1.

Step2: Calculate the sum of the data values

$4 + 8+1 + 3+8 + 4+1=29$

Step3: Determine the number of data points

There are 7 days, so $n = 7$.

Step4: Calculate the mean

The mean $\bar{x}=\frac{\text{Sum of data values}}{\text{Number of data points}}=\frac{29}{7}\approx4.14$

Answer:

$\frac{29}{7}\approx4.14$
