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: Но: ? Select an answer (please enter a decimal) H: ?v Select an answer (Please enter a decimal) c. The test statistic ? v = (please show your answer to 3 decimal places.) С. d. The p-value = e. The p-value is ?v a f. Based on this, we should Select an answer (Please show your answer to 3 decimal places.) |the null hypothesis. g. Thus, the final conclusion is that ... O 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 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%. O 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%.
