   Question

   A researcher draws a random sample of 200 employees of a multinational. The questionnaire that they filled out contained a question about the respondent’s income. The employer claims that there should be no difference in income between men (group 1) and women (group 2). The researcher expects that women earn less than men and tests this expectation with α = 0.05. Below are the results. The analysis takes account of relevant control variables (not visible in the output).
    
     For this question, use the results of “Equal Variances not Assumed”. The H₀ is not rejected because …

   
   
   1. TRUE: p > α.
   2. FALSE: The value 0 falls within the 95% confidence interval.
   3. FALSE: a and b are both correct.
   4. FALSE: This conclusion is incorrect. H₀ has to be be rejected.
   
   
   1. True
   2. False
   3. False
   4. False
