Of the 397 millionaires surveyed, 44 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: ? v Select an answer please enter a decimal) H1: ? v Select an answer (Please enter a decimal) c. The test statistic ? = (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 population proportion is not significantly different from 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 different from 12%. The data suggest the populaton proportion is significantly different from 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 different from 12%. The data suggest the population proportion is not significantly different from 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%.
