Math Problem Statement

What is the mean temperature of the following data set: 89, 80, 83, 89, 91, 87, 84?

Solution

To find the mean of the given data set, add all the temperatures and divide by the number of data points.

The temperatures are: 89, 80, 83, 89, 91, 87, 84.

  1. Add the temperatures:
    89+80+83+89+91+87+84=60389 + 80 + 83 + 89 + 91 + 87 + 84 = 603

  2. Divide by the number of data points (7):

    603786.1\frac{603}{7} \approx 86.1

So, the mean temperature is approximately 86.1.
