question
the data below are the monthly average high temperatures in new york city from the country studies/area handbook series sponsored by the u.s. department of the army between 1986 and 1998. what is the mean high temperature?
40, 40, 48, 61, 72, 78, 84, 84, 76, 65, 54, 42
provide your answer below:

Explanation:

Step1: Sum all the temperatures

We add up all the given temperature values: \(40 + 40 + 48 + 61 + 72 + 78 + 84 + 84 + 76 + 65 + 54 + 42\)
First, calculate step by step:
\(40+40 = 80\)
\(80 + 48 = 128\)
\(128+61 = 189\)
\(189+72 = 261\)
\(261+78 = 339\)
\(339+84 = 423\)
\(423+84 = 507\)
\(507+76 = 583\)
\(583+65 = 648\)
\(648+54 = 702\)
\(702+42 = 744\)

Step2: Divide by the number of data points

There are 12 data points (since there are 12 months). So we divide the sum by 12: \(\frac{744}{12}=62\)

Answer:

62
