Q1. How is the relative frequency of an interval computed? A) Dividing the frequency of that interval by the sum of all frequencies. B) Dividing the sum of the two interval limits by 2. C) Subtracting the lower limit of the interval by the upper limit.
Q2. Given the following frequency distribution: Return Frequency -10% up to 0% 5 0% up to 10% 7 10% up to 20% 9 20% up to 30% 6 30% up to 40% 3 What is the relative frequency of the 0% to 10% interval? A) 40.0%. B) 23.3%. C) 33.3%.
