A PC maker asks 1,000 people whether they've updated their software to the latest version. The survey results are 592 say yes, 198 say no and 210 do not respond. Generate the relative frequency table based off of the data. Why would you need to include the non-responders in your table, even though they don't answer your question?

The pie chart below represents a random sample of 76 people, 22 females and the remaining are males. How could the pie chart below be improved?(couldnt find a picture but basically a simple pie chart that showed 60% blue and 22% red)
