   Question

   Suppose that a two-sided significance test for a population slope in a regression has a p-value that is lower than 0.05. Then the 95% confidence interval for the estimated population slope..

   
   
   1. TRUE: does not contain 0.
   2. FALSE: contains 0.
   3. FALSE: may contain or not contain 0 (we are not sure).
   4. FALSE: contains the true population slope.
   
   

   Solution

   It does not contain 0. since the P-value of the test with H₀: b=0 is lower than 5%, then 0 is not in the range of possible values according to the 95% confidence interval.

   
   
   1. True
   2. False
   3. False
   4. False
