Question
The output to the right shows the regression of the 2010 on the 2011 cost of living index for the most expensive cities in the world in 2011, where Index 2011 is the response variable. Use the output below to complete parts.
State the hypotheses about the slope 1 for both a) and b)
a) The 2011 cost of living index of a city (is or is not) related to the 2010 index 1(equals= or not equals )
b) a) The 2011 cost of living index of a city (is or is not) related to the 2010 index 1(equals= or not equals )
Find the P-value ______
Use the t-model to test the hypothesis. t = ______
Predictor Intercept Index 2010 s-9.16 P-value 0.2887 0.2972 Coeff SE(Coeff) t-ratio 1.10 13.75 12.54 0.228 0.211 1.08 R-Sq = 44.1%Explanation / Answer
We use the table to solve the question:
Answer to the question as follows:
a. The hypothesis will be developed as:
Ho: B1 = .228
Ha: B1! = .228
b. The p-value is .2972
The t-model to test the hyppthesis , is t = 1.08
