This activity, which acts as a learning review, is a solution of the questions 1 & 2 of the MM CAS 2003 Exam 2. Students use the Derive software to solve problems.

Before the Activity

See the attached PDF / DFW file for solutions to the questions, and print the file for the class

During the Activity

Distribute the pages to the class.

In this activity, students will:

Find the probability of the given situation using the cumulative distribution function NORMAL

Understand that the sum of the probabilities should add up to 1

Determine the mean by multiplying the profit by probability and summing

Declare a function definition

Evaluate the function for the value for which the ramp is highest

Calculate the derivative of the function and find the gradient of the ramp

Understand that since the gradient is a sine function with amplitude 1, it must always be less than or equal to 1

Find the area

After the Activity

Review student results:

As a class, discuss questions that appeared to be more challenging
