We often deal with weighted means, in which different data values carry different weights in the
calculation of the mean. For example, if the final exam counts for 50% of your final grade and 2
midterms each count for 25%, then you must assign weights of 50% and 25% to the final and
midterms, respectively, before computing the mean score for the term. Apply the idea of
weighted mean in the following exercise. A student has completed 15 credits in the table to the
right during one semester. Grades are weighted so that A=4.0; A = 3.7; B+ =34; B=3.0;
B-=27; C+=24 and C=2.0. Answer parts a and b below.
