Math Problem Statement

The following dot plot represents student scores on both the Unit 1 and Unit 2 math tests. Scores are in whole number increments.

Part 1: Looking at the data plots, which test do you think the students scored better on? Use complete sentences in your answer and explain your reasoning.

Part 2: Calculate the mean (rounded to the nearest whole number) for both Unit 1 and Unit 2 tests.

Part 3: Do your results from Part 2 prove or disprove your hypotheses from Part 1? Use complete sentences in your answer and explain your reasoning.

Solution

I see that you’ve mentioned a dot plot for student scores on Unit 1 and Unit 2 math tests, but it seems that the plot itself is not visible here. To properly assist you with the analysis and calculations, could you please upload the image of the dot plot, or describe the data points for both Unit 1 and Unit 2 tests?

Once I have the information, I will be able to:

  1. Analyze which test the students performed better on.
  2. Calculate the means for both Unit 1 and Unit 2.
  3. Compare the results to support or refute the hypotheses.

Looking forward to the details!
