Only about 16% of all people can wiggle their ears. Is this percent lower for millionaires? Of the 313 millionaires surveyed, 44 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: ? y Select an answer v (please enter a decimal) H1: ? |Select an answer v (Please enter a decimal) c. The test statistic ? 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 ? v a f. Based on this, we should | Select an answer v| the null hypothesis. g. Thus, the final conclusion is that ... The data suggest the populaton proportion is significantly lower than 16% at a = 0.01, so there is statistically significant evidence to conclude that the population proportion of millionaires who can wiggle their ears is lower than 16%. The data suggest the population proportion is not significantly lower than 16% 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 16%. The data suggest the population proportion is not significantly lower than 16% 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 16%
