Relative Frequency Questions
Not what you're looking for?
Use the relative frequency table to the right (attached) to answer the following questions:
a) How many classes are in the table?
b) What is the class width?
4. The following data consists of the weights, in pounds, of 25 high school students: 195, 206, 165, 105, 340, 210, 195, 108, 195, 145, 180, 210, 104, 195, 100, 212, 110, 206, 220, 142, 185, 235, 280, 115, 140
a) Construct a table that gives the frequency and relative frequency distribution of this data. Use 7 classes for the class width and start the first interval with 100. Be sure to round up to the next interger for your class width.
b) Compute the five-number summary of this data set.

- "GREAT JOB!!!"
- "Hello, thank you for your answer for my probability question. However, I think you interpreted the second and third question differently than was meant, as the assumption still stands that a person still independently ranks the n options first. The probability I am after is the probability that this independently determined ranking then is equal to one of the p fixed rankings. Similarly for the third question, where the x people choose their ranking independently, and then I want the probability that for x people this is equal to one particular ranking. I was wondering if you could help me with this. "
