Only about 17% of all people can wiggle their ears. Is this percent lower for millionaires? Of the 377 millionaires surveyed, 57 could wiggle their ears. What can be concluded at the αα = 0.10 level of significance?

  1. For this study, we should use    
  2. The null and alternative hypotheses would be:

 H0:H0:             (please enter a decimal)

 H1:H1:             (Please enter a decimal)

  1. The test statistic     =  (please show your answer to 3 decimal places.)
  2. The p-value =  (Please show your answer to 3 decimal places.)
  3. The p-value is     αα
  4. Based on this, we should      the null hypothesis.
  5. Thus, the final conclusion is that ...
    • The data suggest the population proportion is not significantly lower than 17% at αα = 0.10, so there is statistically significant evidence to conclude that the population proportion of millionaires who can wiggle their ears is equal to 17%.
    • The data suggest the populaton proportion is significantly lower than 17% at αα = 0.10, so there is statistically significant evidence to conclude that the population proportion of millionaires who can wiggle their ears is lower than 17%.
    • The data suggest the population proportion is not significantly lower than 17% at αα = 0.10, so there is statistically insignificant evidence to conclude that the population proportion of millionaires who can wiggle their ears is lower than 17%.
