Hawaii Teachers’ Salary problem

In April of 2001, all 250 public schools in Hawaii were closed because the teachers went on strike. The teachers were demanding higher salaries. According to The Chicago Tribune (April 18, 2001), the teacher’s union asserted that Hawaii’s high cost of living and low salaries spurred high turnover and made recruiting qualified educators from the mainland difficult. At that time, Hawaii’s average salary, at $40,416, ranked 18th among the 50 states and the District of Columbia, but their cost of living ranked first. You’ve been hired as a statistical consultant to examine this issue. The question asked of you is whether or not the teacher’s in Hawaii had a right to strike because of low salaries. That is, should Hawaii’s teachers be paid more after considering the cost of living in Hawaii? And, if so, what kind of raise should the teacher’s get to increase their pay to the appropriate level after considering the cost of living in Hawaii? To answer these questions, analyze the data (average salary of teachers in all 50 states and the District of Columbia and a cost of living indicator for all 50 states and the District of Columbia from 2001) in the teachers.csv data set on Canvas. Your answer will need to be supported by the results of a proper simple linear regression analysis.

• Which variable is the response variable and which is the explanatory variable?

• Should you include Hawaii in your analysis? Why or why not?

• Is cost of living a significant predictor of teachers’ salaries? If so, how can you use the cost of living to answer the question of interest?

• NOTE: YOU DO NOT HAVE TO ASSESS THE CONDITIONS FOR DOING A SIMPLE LINEAR REGRESSION ANALYSIS FOR THIS PROBLEM!   

Explanation / Answer

In this case we need to find out relationship between Salery of a teacher and cost of living in Havai.

1) Response variable is known as dependent variable and Explanatory variable is also known Independent variable.

In our case we need to find out How much salery raise that teachers should get comapring with high cost of living in Havai.

So Y i.e Response variable = Salery of teachers in all 50 states

X i.e expalnatory varoable = Cost of living for all 50 states
