I really need help answering these questions! Please help Graph the frequency distribution as a histogram graph. Use StatDisk to draw the graph. Describe the histogram and choose one of the measures of central tendency to interpret this data set. Carry all calculations and the answer to 4 decimal places unless otherwise noted. For example, the number "123.0000" has been carried and reported to 4 decimal places. (Yes, trailing zeros count.) The county library staff has recorded the number of...
