Question
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= 885 and the test statistic is t= 57.892. Use technology to find the P-value.
State the null and alternative hypotheses.
Ho: H = 2.84
Hi:p > 2.84
(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.)
