Question

Only about 15% of all people can wiggle their ears. Is this percent different for millionaires? Of the 302 millionaires surveyed, 36 could wiggle their ears. What can be concluded at the α

= 0.10 level of significance?

For this study, we should use

The null and alternative hypotheses would be:

H0:

(please enter a decimal)

H1:

(Please enter a decimal)

The test statistic
= (please show your answer to 3 decimal places.)
The p-value = (Please show your answer to 3 decimal places.)
The p-value is

Based on this, we should
the null hypothesis.
Thus, the final conclusion is that ...
- The data suggest the population proportion is not significantly different from 15% at α
= 0.10, so there is statistically insignificant evidence to conclude that the population proportion of millionaires who can wiggle their ears is different from 15%.
The data suggest the populaton proportion is significantly different from 15% at α
= 0.10, so there is statistically significant evidence to conclude that the population proportion of millionaires who can wiggle their ears is different from 15%.
The data suggest the population proportion is not significantly different from 15% at α

= 0.10, so there is statistically significant evidence to conclude that the population proportion of millionaires who can wiggle their ears is equal to 15%.
