![5.) Draw a density curve and use the calculator to determine the probability. Write the calculator function.
A professor believes that if a class is allowed to work on an examination as long as desired, the times spent
by the students would be approximately normally distributed with mean 70 minutes and standard deviation 5
minutes. What is the probability that a student will take between 60 minutes and 75 minutes to finish an exam?

= -1.4
NORM SDIST (-1.4)
= 0.080751
6.) Draw a density curve and use the calculator to determine the probability. Write the calculator function.
Given the information for problem #5, the Professor would like the end the exam when 90% of the students have
turned in their exam, how much time should she allocate for the exam?](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fc325ae8c-b295-4c41-8bbb-ed3ef941950f%2F0df331e4-cfe6-4ac2-85da-1b707cf98939%2Fo312qz7_processed.jpeg&w=3840&q=75)
