Answer
Answer:

Explanation:
Step1: Count data - points
There is 1 '4', 2 '5's, 3 '6's, 7 '7's, 4 '8's, 1 '9', 1 '10'.
Step2: Calculate sum of data
[4\times1 + 5\times2+6\times3 + 7\times7+8\times4+9\times1+10\times1=4 + 10+18+49+32+9+10 = 132]
Step3: Calculate number of data - points
[1 + 2+3+7+4+1+1=19]
Step4: Calculate the mean
(\text{Mean}=\frac{132}{19}\approx 6.95\approx7) The mean describes the center of a distribution.
