(a) Express the null hypothesis and the alternative hypothesis in symbolic form for the following claim. A manager claims that the average lunch break is more than 0.4 hours long. O Ho: p= 0.4 vs. H: p< 0.4 O Họ: 4 = 0.4 vs. H: µ < 0.4 O Ho: H = 0.4 vs. H: µ # 0.4 O Ho: p = 0.4 vs. H;: p> 0.4 O Họ: 4 = 0.4 vs. H: µ > 0.4 O Ho: p= 0.4 vs. H;: p # 0.4 (b) State the indicated conclusion in nontechnical terms, being sure to address the original claim. An entomologist writes an article in a scientific journal claiming that at most 1.48% of male fireflies are unable to produce light due to a genetic mutation. A hypothesis test of the claim has been conducted, and the decision from that test is to fail to reject Ho. O There is not sufficient evidence to warrant rejection of the claim that the true proportion is at most 1.48%. O There is sufficient evidence to warrant rejection of the claim that the true proportion is at most 1.48%. OThere is not sufficient evidence to support the claim that the true proportion is at most 1.48%. O There is sufficient evidence to support the claim that the true proportion is at most 1.48%.
