Only about 15% of all people can wiggle their ears. Is this percent higher for millionaires? Of the 347 millionaires surveyed, 62 could wiggle their ears. What can be concluded at the αα = 0.01 level of significance? For this study, we should use The null and alternative hypotheses would be: H0: _______ (please enter a decimal) H1: _________ (Please enter a decimal) The test statistic = ______ (please show your answer to 3 decimal places.) The p-value = _________ (Please show your answer to 3 decimal places.) Thus, the final conclusion is that ... The data suggest the population proportion is not significantly higher than 15% at αα = 0.01, so there is statistically significant evidence to conclude that the population proportion of millionaires who can wiggle their ears is equal to 15%. The data suggest the populaton proportion is significantly higher than 15% at αα = 0.01, 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 αα = 0.01, so there is statistically insignificant evidence to conclude that the population proportion of millionaires who can wiggle their ears is higher than 15%.
