Construct a frequency table for the number of novels read.
|Novels Read |Students |
|0 |7 |
|1 |11 |
|2 |9 |
|3 |3 |
|4 |2 |
|5 |2 |
|6 |2 |
|7 |4 |
|Total |40 |
2) The frequency table shows the weights in ounces of 30 stones
Weight (oz) Number of Stones
1.2-1.6 5
1.7-2.1 2
2.2-2.6 5
2.7-3.1 5
6. 13
Use the above information to construct a cumulative frequency table for the data.
|Weight (oz.) of Stones |Frequency |Relative Frequency |Cumulative Frequency |
|1.2 – 1.6 |5 |5/30 = 0.17 |5 |
|1.7 – 2.1 |2 |2/30 = 0.06 |2 + 5 = 7 |
|2.2 – 2.6 |5 |5/30 = 0.17 |5...
