The claim is that smokers have a mean cotinine level greater than the level of 2.84 ng/mL found for nonsmokers. (Cotinine is used as a biomarker for exposure to nicotine.) The sample size is n = 739 and the test statistic is t = 52.124. Use technology to find the P-value. Based on the result, what is the final conclusion? Use a significance level of 0.05.
State the null and alternative hypotheses.
H0: p
H1: H
(Type integers or decimals. Do not round.)
The test statistic is
(Round to two decimal places as needed.)
The P-value is
(Round to three decimal places as needed.)
Based on the P-value, there sufficient evidence at a significance level of 0.05 to the claim that smokers have a mean cotinine level greater than the level of 2.84 ng/mL found for nonsmokers.
