QUIZLET 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) through (d) below, using your distribution, find the probability that the study time in the past week for the student selected would have been in each of the following ranges. (a) 30-39 hours 0.625 (Type an integer or a decimal.) (b) 40-59 hours 3.125 (Type an integer or a decimal.) (c) fewer than 30 hours 4.625 (Type an integer or a decimal.) (d) at least 50 hours nothing (Type an integer or a decimal.)
