Weighted MeanNote: When different data values (?) are assigned different weights (?), we can compute a weighted mean.?̅= ∑(? ∙ ?) ∑ ?Your GPA is computed as a weighted mean. The weights are the units/credits and the values are asfollows:An A is worth 4 pts, B 3pts, C 2pts, D 1 pt, F 0pt1) What would your semester GPA be if you earned an A in a 3 unit English class and a 4 unit Chemistryclass, a B in a 5 unit Math class, and a C in a 3 unit History class?
