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.

With Z = .98, that is not even one standard deviation below the mean.
The null hypothesis looks believable.
