Only about 15% of all people can wiggle their ears. Is this percent higher for millionaires? Of the 380 millionaires surveyed, 76 could wiggle their ears. What can be concluded at the αα = 0.10 level of significance?

For this study, we should use Select an answer t-test for a population mean z-test for a population proportion
The null and alternative hypotheses would be:

H0:H0: ? μ p Select an answer > ≠ = < (please enter a decimal)

H1:H1: ? μ p Select an answer < > ≠ = (Please enter a decimal)

The test statistic ? z t = (please show your answer to 3 decimal places.)
The p-value = (Please show your answer to 3 decimal places.)
The p-value is ? ≤ > αα
Based on this, we should Select an answer fail to reject accept reject the null hypothesis.
Thus, the final conclusion is that ...
- The data suggest the population proportion is not significantly higher than 15% at αα = 0.10, so there is statistically insignificant evidence to conclude that the population proportion of millionaires who can wiggle their ears is higher than 15%.
- The data suggest the population proportion is not significantly higher than 15% 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 15%.
- The data suggest the populaton proportion is significantly higher than 15% at αα = 0.10, so there is statistically significant evidence to conclude that the population proportion of millionaires who can wiggle their ears is higher than 15%.
