What is mean of the data set?

" Mean of the data set is defined as the ratio of total of all given data set to the total number of numbers."

Formula used

Mean $=\frac{x_{1} + x_{2} + x_{3} + x_{4}+ ...+ x_{n}}{n}$

$x_{n} =$ value of each data set

$n=$ total number of terms in data set

According to the question,

Given data set,

$29, 38, 45, 31, 50, 58, 62$

$n = 7$

Substitute the value in the formula of mean we get,

Mean $= \frac{29+ 38+ 45+ 31+ 50 + 58 + 62}{7}$

          $= \frac{313}{7}$

         $= 44.7$°F (nearest tenth)
