Only about 12% of all people can wiggle their ears. Is this percent different for millionaires? Of the 312 millionaires surveyed, 41 could wiggle their ears. What can be concluded at the αα = 0.10 level of significance? A.) The null and alternative hypotheses would be: H0:H0: ? p μ Select an answer ≠ = > < (please enter a decimal) H1:H1: ? μ p Select an answer = > ≠ < (Please enter a decimal) B.) The test statistic ? t z = (please show your answer to 3 decimal places.) C.) The p-value = (Please show your answer to 3 decimal places.) Thus, the final conclusion is that ... The data suggest the population proportion is not significantly different from 12% at αα = 0.10, so there is statistically insignificant evidence to conclude that the population proportion of millionaires who can wiggle their ears is different from 12%. The data suggest the populaton proportion is significantly different from 12% at αα = 0.10, so there is statistically significant evidence to conclude that the population proportion of millionaires who can wiggle their ears is different from 12%. The data suggest the population proportion is not significantly different from 12% at αα = 0.10, so there is statistically significant evidence to conclude that the population proportion of millionaires who can wiggle their ears is equal to 12%.

Question
Only about 12% of all people can wiggle their ears. Is this percent different for millionaires? Of the 312 millionaires surveyed, 41 could wiggle their ears. What can be concluded at the αα = 0.10 level of significance?
A.) The null and alternative hypotheses would be:
H0:H0: ? p μ Select an answer ≠ = > < (please enter a decimal)
H1:H1: ? μ p Select an answer = > ≠ < (Please enter a decimal)
B.) The test statistic ? t z = (please show your answer to 3 decimal places.)
C.) The p-value = (Please show your answer to 3 decimal places.)
Thus, the final conclusion is that ...
- The data suggest the population proportion is not significantly different from 12% at αα = 0.10, so there is statistically insignificant evidence to conclude that the population proportion of millionaires who can wiggle their ears is different from 12%.
- The data suggest the populaton proportion is significantly different from 12% at αα = 0.10, so there is statistically significant evidence to conclude that the population proportion of millionaires who can wiggle their ears is different from 12%.
- The data suggest the population proportion is not significantly different from 12% at αα = 0.10, so there is statistically significant evidence to conclude that the population proportion of millionaires who can wiggle their ears is equal to 12%.
