Answer the following questions in the response area, when doing intermediate steps round to 4 decimal places, round your answers to 2 decimal places:

a. What is the predicted unemployment rate when HSDegree = 70%, BaDegree = 18%, FemHead = 12%, and MedAge = 36 (show your work you might get partial credit)

b. When a county's percent of the population earning a Bachelor's Degree increases by one percentage point, how much and in what direction does the Unemployment Rate change?

c. List the independent variable(s).

d. How much of the variation in Unemployment rate is explained by this regression model?

e. At the one percent significance level, does an increase in Bachelor degree earning decrease unemployment rate, why? (if work is needed, show the work)

Explanation / Answer

Answer:

Answer the following questions in the response area, when doing intermediate steps round to 4 decimal places, round your answers to 2 decimal places:

unemployment rate = 9.6570+0.0604*HSDegree (%)-0.1693*BaDegree (%)-0.0112*FemHead (%)-0.0607*MedAge (years)

predicted unemployment rate =9.6570+0.0604*70-0.1693*18-0.0112*12-0.0607*36

=8.518

=8.52 ( 2 decimals)

An increase of one % in Bachelor degree earning, there is decrease unemployment rate by 0.1693.

HSDegree (%), BaDegree (%), FemHead (%), MedAge (years)

Multiple R = 0.6406

64.06% explained.

Calculated t=-4.4496, P=0.0000 which is < 0.01 level. The coefficient is significantly decreasing.

An increase of one % in Bachelor degree earning, decrease unemployment rate by 0.1693.
