Only about 17% of all people can wiggle their ears. Is this percent lower for millionaires? Of the 319 millionaires surveyed, 45 could wiggle their ears. What can be concluded at the a = 0.01 level of significance? a. For this study, we should use Select an answer b. The null and alternative hypotheses would be: Ho: (please enter a decimal) H1: (Please enter a decimal) c. The test statistic t v (please show your answer to 3 decimal places.) d. The p-value - (Please show your answer to 3 decimal places.) e. The p-value is sva f. Based on this, we should fail to reject g. Thus, the final conclusion is that ... v the null hypothesis. O The data suggest the populaton proportion is significantly lower than 17% at o = 0.01, so there is statistically significant evidence to conclude that the population proportion of millionaires who can wiggle their ears is lower than 17%. OThe data suggest the population proportion is not significantly lower than 17% at a = 0.01, so there is statistically insignificant evidence to conclude that the population proportion of millionaires who can wiggle their ears is lower than 17%. O The data suggest the population proportion is not significantly lower than 17% at a 0.01, so there is statistically significant evidence to conclude that the population proportion of millionaires who can wiggle their ears is equal to 17%.
