a. For this study, we should use z-test for a population proportion
b. The null and alternative hypotheses would be:
Ho: pv=

(please enter a decimal)
H1: pv|<
V 0.18

c. The test statistic zv =
-0.550|
(please show your answer to 3 decimal places.)
d. The p-value =
(Please show your answer to 3 decimal places.)
e. The p-value is ?a
f. Based on this, we should Select an answerv the null hypothesis.
g. Thus, the final conclusion is that ...
O The data suggest the population proportion is not significantly lower than 18% at a = 0.01, so
there is statistically insignificant evidence to conclude that the population proporti
millionaires who can wiggle their ears is lower than 18%.
of
O The data suggest the populaton proportion is significantly lower than 18% at a = 0.01, so there
is statistically significant evidence to conclude that the population proportion of millionaires
who can wiggle their ears is lower than 18%.
O The data suggest the population proportion is not signtficantly lower than 18% at a = 0.01, so
