   Question

   We run a hypothesis testing for a proportion with the following null and alternative hypothesis:

   H₀: p = 0.50
   H_a: p > 0.50

   The observed z-score is -1.88. The corresponding P-value (see Table A: Standard Normal Cumulative Probabilities) is 3.01% (actually 0.0301). This means that there is a 3.01% probability that …

   
   
   1. FALSE: the z-score is between -1.88 and 0.00.
   2. FALSE: the z-score is between -1.88 and 1.88.
   3. FALSE: the z-score is -1.88 or higher.
   4. TRUE: the z-score is -1.88 or lower.
   5. FALSE: the z-score is between -1.96 and -1.88.
   
   
   1. False
   2. False
   3. False
   4. True
   5. False
