Question

what is the mean? if the answer is a decimal, round it to the nearest tenth. 81 68 69 77 71

Explanation:

Step1: Sum the numbers

To find the mean, first sum the given numbers: \(81 + 68 + 69 + 77 + 71\). Let's calculate that: \(81+68 = 149\), \(149+69 = 218\), \(218+77 = 295\), \(295+71 = 366\).

Step2: Divide by the count

There are 5 numbers, so divide the sum by 5: \(\frac{366}{5}=73.2\).

Answer:

73.2
