Statistics 2101 Homework Assignment #2 1. The number of times an event occurs is called a frequency 2. For the class interval 60-69, the upper apparent limit is 69 3. The real limits for the class interval 101-110 are 100.5 and 110.5 4. The class-interval size is 10, and the lower apparent limit is 16. The upper apparent limit would be 25. a. 25 c. 25.5 b. 26 d. 24 5. According to the guidelines for the construction of grouped frequency distributions, the smallest class interval size possible is 3. a. 1 c. 3 b. 2 d. 5 Class Interval f cf rcf 75-77 02 37 1.00 72-74 06 35 .95 69-71 10 29 .78 66-68 08 19 .51 63-65 07 11 .30 60-62 04 04 .11 6. The relative frequency for the class interval 69-71 is ______________. a. 10 c. .78 b. 29 d. .27 7. The value for f would be 37 8.
