Answer :

Using the weighted mean, it is found that your final grade is of 91%.

What is the weighted mean?

The weighted mean is given by the sum of all elements in a data-set multiplied by it's weight, divided by the sum of the weights.

For this problem, the grades are given as follows:

  • 86% with a weight of 1.
  • 94% with a weight of 1.
  • 92% with a weight of 2.

Hence the mean is:

M = (86 + 94 + 2 x 92)/4 = 91.

Your final grade is of 91%.
