A candy bar manufacturer is interested in trying to estimate how sales are influenced by the price of their product. To do this, the company randomly chooses 6 small cities and offers the candy bar at different prices. Using candy bar sales as the dependent variable, the company will conduct a simple linear regression on the data below:
City
Price ($)
1.30
1.60
1.80
2.00
River Falls
Hudson
Ellsworth
Prescott
To test that the regression coefficient, B₁, is not equal to 0,what would be the critical values? Use a = 0.05.
Let t0.025:24.303; 0.025:3 = 3.182;t0.05:22.920; to.05:3 2.353
