Question

the numbers of words defined on randomly selected pages from a dictionary are shown below find the mean, median, and mode of the listed numbers
64 76 72 66 69 65 57 61 71 52
what is the mean? select the correct choice below and, if necessary, fill in the answer box within your choice.
a. the mean is (round to one decimal place as needed )
b. there is no mean

Explanation:

Step1: Sum the numbers

We have the numbers: 64, 76, 72, 66, 69, 65, 57, 61, 71, 52.
Summing them up: \(64 + 76 + 72 + 66 + 69 + 65 + 57 + 61 + 71 + 52\)
\(= (64 + 76) + (72 + 66) + (69 + 65) + (57 + 61) + (71 + 52)\)
\(= 140 + 138 + 134 + 118 + 123\)
\(= 140+138 = 278\); \(278+134 = 412\); \(412+118 = 530\); \(530+123 = 653\)

Step2: Divide by the number of terms

There are 10 numbers. So the mean is \(\frac{653}{10}=65.3\)

Answer:

A. The mean is \(65.3\) (Round to one decimal place as needed )
