Worksheet problems: NOTE: Number one was not graded for accuracy. 2 points were given for the histogram/graph and 2 points were given for the density curve…whether the graph and curve were truly correct or not. Number two was graded for accuracy (worth 5 points total)…the expected frequencies could be calculated a few ways…and because the problem wasn’t specific, I counted any of the ways I felt appropriate IF AND ONLY IF you should some work to indicate how you got the expected frequencies!! Otherwise, some points were docked for the lack of work. The following solutions are reasonable answers for the worksheet.
