The claim is that smokers have a mean cotinine level greater than the level of $2.84 \mathrm{ng} / \mathrm{mL}$ found for nonsmokers. (Cotinine is used as a biomarker for exposure to nicotine.) The sample size is $n=869$ and the test statistic is $t=53.714$. 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. $\mathrm{H}_{0}: \mu$ $\square$ $\square$ $\mathrm{H}_{1}: \mu$ $\square$ $\square$ (Type integers or decimals. Do not round.)
