Question

If you test the (one sample) null hypothesis that the population proportion p ¡Ü 0.3 and you get the test statistic value of z = -0.98, then using a 5% ignificance level, Question 18 options:
 the alternative hypothesis looks believable.  
 the null hypothesis looks believable.  
 the null and alternative hypotheses both look believable.  
 none of the above.
