State the null and alternative hypotheses: H0: μ | ≠, <, =, or > _________ H1: μ | ≠, ≥ , =, ≤ , or = _________ The claim is that smokers have mean cotinine level greater than the level of 2.84 ng/mL found for nonsmokers. (Cotinine is used as a biomarker for exposure tonicotine.) The sample size is n = 911 and the test statistic is t= 56.944. Use technology to find the P-value. Based on the result, what is the final conclusion? Use asignificance level of 0.01.State the null and alternative hypotheses.HoiHH₂₁:μ(Type integers or decimals. Do not round.)C
