I only need Part D.

The following data set outlines the scores students had on an Algebra test. 41 42 43 43 43 43 43 44 44 44 44 45 45 45 45 i) Fill in the frequency table (below) Scores 7 6 5 4 3 2 40 43 44 45 1 39 ii) Draw a dot plot on the graph below. You do not need to show the entire column of dots, only the one on the top representing the frequency of the test score. Score 40 40 41 42 43 44 45 19 41 42 13 43 Frequency 44 45 40
