A poll for the presidential campaign sampled 491 potential voters in June. A primarypurpose of the poll was to obtain an estimate of the proportion of potential voters whofavored each candidate. Assume a planning value of p* = .50 and a 95% confidencelevel.a. For p* = .50, what was the planned margin of error for the June poll?
Here is a data set: Construct a grouped frequency distribution table (GFDT) for this data set. You want 10 classes with a "nice" class width. Your classes should be labeled using interval notation. Each class should contain its lower class limit and each sequential lower class limit should increase by increments of the class width. In that the data appears to be discrete, use a closed-interval to label each class.

Please help solving this showing all the steps.
How to find the class width of a frequency table?
differentiate interquartile range and semi interquartile range in terms of their uses and how to interpret it.
Note: For discrete data set, use this format {#,#,#...#} for continuous data set, write answer using inequality notation
