Statistics Question

Description

We are allowed to do 2 practice exams before the actual exam. the actual exam is tomorrow starting 8 am – 10:30 am were going to have 2 hours to finished it its going to be 14 questions exam. the practice test is the same questions but with different numbers we can practice the questions so were ready for tomorrow I will send you the teachers way how to solve them we have to do exactly the way she did if we don’t do like she did she won’t give me full points on the exam.

The exam is going to cover all this

Content:

This midterm covers sections 13, 14, 15, 16, 17, and 18.

The exam is worth 100 raw points, consists of 13 questions, and is scheduled for one hour and twenty minutes; however, the Canvas time limit may exceed one hour and twenty minutes.

Remember that if you start the exam and lose connection or close the window or have a power outage, the exam clock will CONTINUE to wind down!! Whatever the Canvas time limit, remember that the exam is only available during class, and you will be kicked out no matter when you start the exam!!
