Only about 19% of all people can wiggle their ears. Is this percent different for millionaires? Of the 365 millionaires surveyed, 62 could wiggle their ears. What can be concluded at the = 0.01 level of significance?

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

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

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

1. The test statistic ? z t = (please show your answer to 3 decimal places.)
2. The p-value = (Please show your answer to 3 decimal places.)
3. The p-value is ? >
4. Based on this, we should Select an answer accept reject fail to reject the null hypothesis.
5. Thus, the final conclusion is that ...

• The data suggest the populaton proportion is significantly different from 19% at = 0.01, so there is statistically significant evidence to conclude that the population proportion of millionaires who can wiggle their ears is different from 19%.
• The data suggest the population proportion is not significantly different from 19% at = 0.01, so there is statistically insignificant evidence to conclude that the population proportion of millionaires who can wiggle their ears is different from 19%.
• The data suggest the population proportion is not significantly different from 19% at = 0.01, so there is statistically significant evidence to conclude that the population proportion of millionaires who can wiggle their ears is equal to 19%.
