Answer 1

In order to compute mean, you have to add all values of the data set up and divide by the number of data values there are.

In this case, the total sum of all data values is: 81+88+69+65+87=390

The number of data values is 5

To compute mean: 390/5=78

The mean height of the corn stalks is 78cm (C)

Answer 2

The answer is C) 78, because to get the mean answer you have to add them all and what you get (390) you have to divide it by the amount of numbers (5).
