The dot plots below show the test scores of some mathematics students and some science students: Two dot plots are shown one below the other. The top and the bottom plots have the title Mathematics Students and Science Students respectively. Below the line for each dot plot is written Mark. The markings on each line are from 30 to 50 at intervals of 1. For the top plot there are two dots each for 34 and 40 and 1 dot each for 32, 33, 35, 37, and 39. For the bottom plot there are 2 dots each for 43, 46 and 49 and 1 dot each for 41, 42, and 47. Based on visual inspection of the dot plots, which group of students appears to have the larger average score?

A. The mathematics students

B. The science students

C. Both groups are similar.

D. Not enough information is available to draw a conclusion.

Oswaldo Olsen · Answer 1

B. The science Students

Step-by-step explanation:

This is a simple answer. to find the average, or the mean. So you add up all of the math scores and divide it by 9, which gives you 36. Then, you add up all of the science scores and divide them by 9, which gives you about 45. So if the science students are on the bottom plot, then it is B, the science students.
