Hi please complete only C & D. Everything else is done thank you
Only about 20% of all people can wiggle their ears. Is this percent different for millionaires? Of the 393 millionaires surveyed, 94 could wiggle their ears. What can be concluded at the a = 0.05 level of significance? a. For this study, we should use z-test for a population proportion ✓ b. The null and alternative hypotheses would be: Ho: Р H₁: pv = 1.933 α 0.20 0.20 c. The test statistic z v d. The p-value = e. The p-value is > v f. Based on this, we should fail to reject g. Thus, the final conclusion is that ... (please enter a decimal) ✓(Please enter a decimal) x (please show your answer to 3 decimal places.) (Please show your answer to 3 decimal places.) the null hypothesis. The data suggest the population proportion is not significantly different from 20% 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 20%. O The data suggest the populaton proportion is significantly different from 20% 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 20%. O The data suggest the population proportion is not significantly different from 20% 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 20%.
