Only about 12% of all people can wiggle their ears. Is this percent lower for millionaires? Of the 369 millionaires surveyed, 33 could wiggle their ears. What can be concluded at the a= 0.05 level of significance? a. For this study, we should use Select an answer b. The null and alternative hypotheses would be: Ho: H₁: ? Select an answer Select an answer (please enter a decimal) (Please enter a decimal) c. The test statistic?v= d. The p-value = e. The p-value is ? a f. Based on this, we should [Select an answer the null hypothesis. g. Thus, the final conclusion is that ... (please show your answer to 3 decimal places.) (Please show your answer to 3 decimal places.) The data suggest the population proportion is not significantly lower than 12% at a = 0.05, so there is statistically significant evidence to conclude that the population proportion of millionaires who can wiggle their ears is equal to 12%. O The data suggest the population proportion is not significantly lower than 12% at a = 0.05, so there is statistically insignificant evidence to conclude that the population proportion of millionaires who can wiggle their ears is lower than 12%. O The data suggest the populaton proportion is significantly lower than 12% at a = 0.05, so there is statistically significant evidence to conclude that the population proportion of millionaires who can wiggle their ears is lower than 12%.
