The noon temperatures for seven consecutive days were $80^{\circ}$, $79^{\circ}$, $81^{\circ}$, $85^{\circ}$, $87^{\circ}$, $89^{\circ}$, and $87^{\circ}$ Fahrenheit. What is the mean noon temperature, in degrees Fahrenheit, for the week?
I need to find the mean of a set of data, which is the sum of the data divided by the number of data points. There are seven data points, one for each day of the week. To find the sum, I can add up all the temperatures: $80 + 79 + 81 + 85 + 87 + 89 + 87 = 588$. To find the mean, I can divide the sum by the number of data points: $\frac{588}{7} = 84$. The mean noon temperature, in degrees Fahrenheit, for the week is 84.
