What can be concluded at the a = 0.10 level of significance? a. For this study, we should use Select an answer b. The null and alternative hypotheses would be: Ho: Select an answer H: Select an answer (please enter a decimal) (Please enter a decimal) c. The test statistic? = d. The p-value = e. The p-value is ? a (please show your answer to 3 decimal places.) (Please show your answer to 3 decimal places.) f. Based on this, we should Select an answer the null hypothesis. g. Thus, the final conclusion is that... The data suggest the population proportion is not significantly different from 12% at a = 0.10, 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 = 0.10, 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 = 0.10, so there is statistically significant evidence to conclude that the population proportion of millionaires who can wiggle their ears is equal to 12%.
