Only about 14% of all people can wiggle their ears. Is this percent lower for millionaires? Of the 400 millionaires surveyed, 40 could wiggle their ears. What can be concluded at the a = 0.10 level of significance? a. For this study, we should use Select an answer b. The null and alternative hypotheses would be: Ho: ? v Select an answer ▼ (please enter a decimal) Hj: ? v Select an answer ▼ (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 ... O The data suggest the population proportion is not significantly lower than 14% at a = 0.10, so there is statistically insignificant evidence to conclude that the population proportion of millionaires who can wiggle their ears is lower than 14%. O The data suggest the populaton proportion is significantly lower than 14% at a = 0.10, so there is statistically significant evidence to conclude that the population proportion of millionaires who can wiggle their ears is lower than 14%. O The data suggest the population proportion is not significantly lower than 14% at a = 0.10, so there is statistically significant evidence to conclude that the population proportion of millionaires who can wiggle their ears is equal to 14%.

Transcribed Image Text:Only about 14% of all people can wiggle their ears. Is this percent lower for millionaires? Of the 400
millionaires surveyed, 40 could wiggle their ears. What can be concluded at the a = 0.10 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 V
(please enter a decimal)
H1:
? v 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
g. Thus, the final conclusion is that ...
the null hypothesis.
O The data suggest the population proportion is not significantly lower than 14% at a = 0.10, so
there is statistically insignificant evidence to conclude that the population proportion of
millionaires who can wiggle their ears is lower than 14%.
O The data suggest the populaton proportion is significantly lower than 14% at a = 0.10, so there
is statistically significant evidence to conclude that the population proportion of millionaires
who can wiggle their ears is lower than 14%.
O The data suggest the population proportion is not significantly lower than 14% at a = 0.10, so
there is statistically significant evidence to conclude that the population proportion of
millionaires who can wiggle their ears is equal to 14%.
