The travel time of 300 students that journey to the University of Manitoba produced the following descriptive statistics: mean = 41.67 minutes standard deviation = 12.37 minutes
Assuming the distribution is normal, use these sample statistics to answer the following questions about the travel time to the University of Manitoba. Sketch a normal curve and shade the relevant areas in each problem:
Question 5: What is the probability that students travelled more than 60 minutes to school? (2 marks) Question 6: What is the probability that students travelled less than 20 minutes to school? (2 marks)
Question 7: What is the probability that students travelled between 30 and 50 minutes to school? (2 marks)
Question 8: What is travel time that is exceed by only 15% of the students?
