Question

Approximately 10%10% of Americans are left-handed (we will treat this as a known population parameter). A study on the relationship between handedness and profession found that in a random sample of 105 lawyers, 16 of them were left-handed.¹ Test the hypothesis that the proportion of left-handed lawyers differs from the proportion of left-handed Americans.

Clearly state the null and alternative hypotheses.

Let pp be the proportion of left-handed lawyers.

Calculate the test statistic and p-value.

Round your answer for the test statistic to two decimal places, and your answer for the p-value to three decimal places.

test statistic = Enter your answer; test statistic

p-value = Enter your answer; p-value

What do we conclude at the 5% significance level? At the 10% significance level?

Significance Level	Conclusion
5%	Choose the answer from the menu; What do we conclude at the 5% significance level? H0H0.
10%	Choose the answer from the menu; What do we conclude at the 10% significance level? H0H0.
