Only about 17% of all people can wiggle their ears. Is this percent lower for millionaires? Of the 319 millionaires surveyed, 45 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: Ho: (please enter a decimal) H1: (Please enter a decimal) c. The test statistic t 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 sva f. Based on this, we should fail to reject g. Thus, the final conclusion is that ... v the null hypothesis. O The data suggest the populaton proportion is significantly lower than 17% at o = 0.01, so there is statistically significant evidence to conclude that the population proportion of millionaires who can wiggle their ears is lower than 17%. OThe data suggest the population proportion is not significantly lower than 17% 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 17%. O The data suggest the population proportion is not significantly lower than 17% 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 17%.

Transcribed Image Text:Only about 17 of all people can wiggle their ears. Is this percent lower for millionaires? Of the 319
millionaires surveyed, 45 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:
Ho: py
(please enter a decimal)
%3D
H: p #
(Please enter a decimal)
c. The test statistic t 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 s a
f. Based on this, we should fail to reject
g. Thus, the final conclusion is that...
the null hypothesis.
OThe data suggest the populaton proportion is significantly lower than 17% 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 17%.
O The data suggest the population proportion is not significantly lower than 17% 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 17%.
O The data suggest the population proportion is not significantly lower than 17% 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 17%.
