Answer:

Answer = D

Step-by-step explanation:

If you add all of the heights up you get 480. divide that by ten (because there were 10 students whose height was taken) then you get 48. therefore, the typical second-grade student is about 48 inches tall.

What is mean?

'Mean is the average of the given numbers and is calculated by dividing the sum of given numbers by the total number of numbers.'

According to the given problem,

Given data = { 44, 45, 47, 49, 48, 48, 49, 50, 48, 52 }

Sum of the given data = 44 + 45 + 47 + 49 + 48 + 48 + 49 + 50 + 48 + 52

                                     = 480

Average of the given heights = [tex]\frac{480}{10}[/tex]

                                                 = 48

Hence, we can conclude,  The typical second-grade student is about 48 inches tall since the average of the given data is 48.
