An empirical probability distribution based on weekly study times for a sample of 40 students is provided to the right. Suppose one of those students was chosen randomly. In parts (a) Class Frequency Relative through (d) below, using your distribution, find the probability that the study time in the past week Limits Frequency for the student selected would have been in each of the following ranges. 10-19 0.275 20-29 0. 150 30-39 0.175 40-49 0.225 (a) 30-39 hours 50-59 0.025 - N (Type an integer or a decimal.) 60-69 0.050 70-79 0.100 Total: n = 40
