Consider the following relative frequency distribution: Class -20 up to 10 -10 up to o up to 10 10 up to 20 20 up to 30 Relative Frequency 0.19 0.22 0.13 0.19 6.27 0-1. Suppose this relative frequency distribution is based on a sample of 46 observations. Construct the frequency distribution Frequency Class -20 up to -10 -10 up to 0 O up to 10 10 up to 20 20 up to 30 Total a-2. How many of the observations are at least-10 but less than 0? Number of observations b-1. Construct the cumulative frequency distribution Class Cumulative Frequency -20 up to -16 10 up to up to 10
b-2. How many of the observations are less than 107 Number of servations
