In an attempt to determine whether a candidate in an upcoming election actually had 60% of the vote, as indicated in a recent poll, his
campaign team ran a simulation. The team members chose 20 randomly selected digits from 0 to 9, with the numbers o through b
representing a success and the numbers 6 through 9 representing not a success. They then ran several trials and observed the following
results:
Proportion 0.52 0.53 0.54 0.55 0.56 0.57 0.58 0.59 0.60 0.61 0.62 0.63 0.64 0.65 0.66 0.67 0.68 0.69
Frequency 1 2 2 6 7 8 12 13 20 14 11 12 10 6 3 5 2 1
Part A: Based on the results in the table, what was the number of trials?
Part B: If you were to construct a dot plot of the 60% proportion simulation table, which proportion(s) would contain the least number of
dots?
Part C: Discuss collaboratively: Use the table to determine accurately the probability of success for all of the trials. How accurate would you
suggest the poll was? Explain.
