Question
Only about 20% of all people can wiggle their ears. Is this percent lower for millionaires? Of the 346
millionaires surveyed, 55 could wiggle their ears. What can be concluded at the a = 0.01 level of
significance?
a. For this study, we should use Select an answer
b. The null and alternative hypotheses would be:
Но:
Select an answer
(please enter a decimal)
H1:
Select an answer v
(Please enter a decimal)
c. The test statistic ? v =
(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 ? v a
f. Based on this, we should Select an answer v the null hypothesis.
g. Thus, the final conclusion is that
...
The data suggest the population proportion is not significantly lower than 20% at a = 0.01, so
there is statistically significant evidence to conclude that the population proportion of
millionaires who can wiggle their ears is equal to 20%.
The data suggest the population proportion is not significantly lower than 20% at a = 0.01, so
there is statistically insignificant evidence to conclude that the population proportion of
millionaires who can wiggle their ears is lower than 20%.

The data suggest the populaton proportion is significantly lower than 20% 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 20%.
