Define relative frequency and conditional relative frequency

The clearness index was determined for the skies over Baghdad for each of the 365 days during a particular year. The following accompanying table summarizes the resulting data. Clearness Index Number of Days (frequency) 0.15 to <0.25 5 0.25 to <0.35 19 0.35 to <0.45 25 0.45 to <0.50 24 0.50 to <0.55 42 0.55 to <0.60 52 0.60 to <0.65 99 0.65 to <0.70 88 0.70 to <0.75 11 (a) Determine the relative frequencies and fill in the following table. (Round your answer to five decimal places if needed.) Class Intervals Frequency Rel. Frequency 0.15 to <0.25 5   0.25 to <0.35 19   0.35 to <0.45 25   0.45 to <0.50 24   0.50 to <0.55 42   0.55 to <0.60 52   0.60 to <0.65 99   0.65 to <0.70 88   0.70 to <0.75 11   (b) Draw the histogram. (Be careful here-the intervals do not all have the same width. Do this on paper. Your instructor may ask you to turn in this graph.)(c) Cloudy days are those with…
