In your biology class, your final grade is based on several
things: a lab score, scores on two major tests, and your score on
the final exam. There are 100 points available for each score.
However, the lab score is worth 17% of your total grade, each major
test is worth 24%, and the final exam is worth 35%. Compute the
weighted average for the following scores: 80 on the lab, 83 on the
first major test, 98 on the second major test, and 95 on the final
exam.

Look at the histogram below, which shows milleage, in miles per gallon (mpg), for a random selection of older passenger cars.t Histogram of mpg 15 14 12 10 12 6 6 8.5 12.5 16.5 20.5 24,5 28.5 32.5 36.5 40.5 mpg (a) Is the shape of the histogram essentially bimodal? O Yes, because the histogram has one peak. O Yes, because the histogram has two peaks. O No, because the histogram has one peak. O No, because the histogram has...
A student recieves test scores of 62, 83 and 91. The students final exam score is 88 and homework score is 76. Each test is worth 20% of the final grade, the final exam is worth 25% of the final grade and homework grade is worth 15% of the final grade. Using weighted average, what is the students numerical grade for the course.
1. Ms. Jackson has three sections of the course "Introduction to Statistics.” The midterm results reveal that class A has an average of 82, class B has an average of 88, and class C has an average of 92. If there were 20 students in class A, 25 students in class B, and 27 students in class C, what is the combined mean (the average for all the three classes)? Show your work. 2. In your Biology class, your final...
Professor Cramer determines a final grade based on attendance, two papers, three major tests, and a final exam. Each of these activities has a total of 100 possible points. However, the activities carry different weights. Attendance is worth 4%, each paper is worth 7%, each test is worth 18%, and the final is worth 28%. (a) What is the average for a student with 85 on attendance, 81 on the first paper, 83 on the second paper, 62 on test...
