A grouped frequency distribution and its corresponding relative frequency distribution based on weekly study times for a sample of 40 students is provided. Suppose one of those students was selected randomly. Using the relative frequency distribution, find the probability that the study time in the past week for the student selected would have been in each of the ranges given in parts (a) through (d).
