7th & 8th Grade Lottery Project
Due date: June 6, 2011
Each week there are two drawings for New Jersey's Pick 6 Lottery in which 6 numbered balls are drawn at random, without replacement, from balls numbered 1, 2, 3, ... 49.
-
Keep a record of the numbers drawn over the next several weeks. (May 10, 2011 through June 3, 2011).
- Draw a graph of your choosing to illustrate the frequency of occurrence of each number.
-
List the frequencies in numerical order. Find the:
- mean
- median
- mode
- range
for the frequency data.
What do you expect the frequency of occurrences of each number to be, if the balls are drawn randomly? Does your data above support the hypothesis that “the balls are drawn randomly?”
Your grade will be based on the following:
- Neatness of the graph you chose. (15 pts.)
- Title and label of the graph. (15 pts.)
- Accuracy of the graph compared to online results. (10 pts.)
- Correctly finding the mean, median, mode, and range of numbers in the data. (40 pts.)
- Answering the expectation question clearly in a well-written paragraph. (10 pts.)
- Answering the hypothesis question clearly in a well-written paragraph. (10 pts.)
