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 = 778 and the test statistic is t = 58.258. Use technology to find the P-value. Based on the result, what is the final conclusion? Use a significance level of 0.10. State the null and alternative hypotheses. Hot H₁ ▼ (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 that smokers have a mean cotinine level greater than the level of 2.84 ng/mL found for nonsmokers. the claim
