Exercise 2-21 Algo Consider the following cumulative frequency distribution: Interval 15 < X S 25 25 X S 35 35 < X S 45 45 < X s 55 Cumulative Frequency 3 6 8 ll a-I. Construct the frequency distribution and the cumulative relative frequency distribution. (Round "Cumulative Relative Frequency" to 3 decimal places.) Interval 15 < x s 25 25 < x s 35 35 < x s 45 45 < x s 55 Cumulative Frequency Relative Frequency a-2. How many observations are more than 35 but no more than 45? Number of observations
