Only about 15% of all people can wiggle their ears. Is this percent higher for millionaires? Of the 328 millionaires surveyed, 56 could wiggle their ears. What can be concluded at the α = 0.10 level of significance? Use the p-value approach. a. For this study, we should use [z-test for a population proportion b. The null and alternative hypotheses would be: Ho: P H₁: pv c. The test statistic z v O d. The p-value = e. The p-value is > ✔ (please enter a decimal) f. Based on this, we should fail to reject Or (Please enter a decimal) (please show your answer to 3 decimal places.) (Please show your answer to 3 decimal places.) the null hypothesis. g. Thus, the final conclusion is that ... O The data suggest the populaton proportion is significantly higher than 15% at a = 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%. The data suggest the population proportion is not significantly higher than 15% at a = 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 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 15%.
