Question

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 is taking an advanced anatomy class in which the midterm and final exams are worth 35​% each and homework is worth 30​% of his final grade. On a​ 100-point scale, his midterm exam score was 86.5 his homework average score was 91.5 and his final exam score was 86.4 Complete parts​ (a) and​ (b) below. a. On a​ 100-point scale, what is the​ student's overall average for the​ class? His overall average is____ (round to the nearest tenth as needed.)
