Answer 1

The mean height of the 17 students in the​ class 68.8 inches.

Explanation

The mean height of all 16 students in the class is 69.0 inches.

As mean is the simple average, so the total height of all 16 students will be: $(69.0*16)= 1104$ inches.

Now, Danielle is 65.6 inches tall. So, the total height of 17 students $= (1104+65.6)=1169.6$ inches.

So, the mean height of the 17 students in the​ class $=\frac{1169.6}{17}= 68.8$ inches.

Answer 2

The mean height of the 17 17 students in the​ class is  68.8 inches.

Mean is the average of a set of numbers. It is determined by adding the ages together and dividing it by the total number of students.

Mean = sum of the ages / total number of students in the class.  

Sum of the ages of the 16 students = 16 x 69 = 1,104.

In order to determine the mean age of 17 students, add Danielle's age to the sum of the ages of the 16 students and then divide by 17.

(1104 + 65.6) / 17 = 68.8 inches
