Relative Frequency Distribution

Consider the following frequency distribution: Interval Frequency 1,000 < x ≤ 1,100 22 1,100 < x ≤ 1,200 38 1,200 < x ≤ 1,300 44 1,300 < x ≤ 1,400 16 a.) Construct the relative frequency distribution. What proportion of the observations are more than 1,100 but no more than 1,200? - b.) Construct the cumulative frequency distribution. How many of the observations are 1,300 or less? - c.) Construct the cumulative relative frequency distribution. What proportion of the observations are 1,300 or less? More than 1,300? -
