Answer to Problem 40E
5.4
Explanation of Solution
Given:
The amount of time (in hours per week) a student utilizes a math-tutoring center roughly follows the normal distribution
Where x is the number of hours.
The graph of the function
The average number of hours per week a student uses the tutoring center is given by the x -coordinate of the highest point of the graph.
In this case the x -value corresponding to the maximum y -value is 5.4.
Conclusion:
The average number of hours per week a student uses the tutoring center is 5.4 hours.
