A statistics professor for STAT 250 wants to investigate how long it takes students to complete Exam 1. The times that it took all 715 STAT 250 students in Spring 2022 were recorded in the data set “Time to Complete Exam 1” found in StatCrunch. The time is recorded in minutes. A student who completed the exam in 50:30 (50 minutes and 30 seconds) would be recorded as 50.5 minutes. Find the proportion of all 50 minutes or more. (X ≥ 50). You can click on the bars of your histogram to help obtain this value. Show the values used for the calculation of the proportion as well as your answer. Round your proportion to four decimal places.
