1. Working with Real Data: Minimum Wage

• Complete the following in your team meeting:

o Complete parts a–e from the Group Activity at the end of section 11.3 in Ch. 11 of the text.

o Discuss any concept that a team member is having a difficult time understanding.

o Examine the importance and applicability of this week’s concepts to each team member and to society in general.

o Plan and work on team assignments or projects.

• Post your team’s solutions from this exercise to the Main forum. Briefly describe how this activity applied to the weekly concepts.

• Post a 150- to 200- word summary to the Main forum from your team’s examination and discussion of the weekly concepts. Update the class on any concept the team had difficulty understanding and what the team did to help each member understand the concept. Include the team’s discussion on the importance of the weekly concepts, and how they can be applied to each team member and society in general.

I will start the years from 0 as the following:

1940 = 0

1968 = 28

1997 = 57

Table is as :

Year | 1940 | 1968 | 1997 |

Wage ($) | 0.25 | 1.60 | 5.15 |

(A) Make a scatterplot of the data in the viewing rectangle [1930, 2010, 10] by [0, 6, 1].

(B) Find a quadratic function given by f(x) = a(x – h)^2 + k that models the data.

a(1940)^2 + b(1940) + c = .25

a(1968)^2 + b(1968) + c = 1.60

a(1997)^2 + b(1997) + c = 5.15

We can reduce the numbers and still get the same effect by subtracting 1940 from everything.

These numbers are more manageable; we just can’t forget to “+40” to the year when we are done.

a(0)^2 + b(0) + c = .25 From this we see that c = .25 This is a given and we should write...
