A report claims thatnbsp at most 74% of lung cancer deaths are due to tobacco use. State Upper H 0 and Upper H Subscript a in words and in symbols. Then determine whether the hypothesis test for this claim is left-tailed, right-tailed, or two-tailed. Explain your reasoning. State the null hypothesis in words and in symbols. Choose the correct answer below. A. The null hypothesis expressed in words is, "the proportion of all lung cancer deaths that are due to tobacco use isnbsp at most 0.74." The null hypothesis is expressed symbolically as, "Upper H 0: pless than or equals0.74." B. The null hypothesis expressed in words is, "the proportion of all lung cancer deaths that are due to tobacco use isnbsp not 0.74." The null hypothesis is expressed symbolically as, "Upper H 0: pnot equals0.74." C. The null hypothesis expressed in words is, "the proportion of all lung cancer deaths that are due to tobacco use isnbsp at least 0.74." The null hypothesis is expressed symbolically as, "Upper H 0: pgreater than or equals0.74." D. The null hypothesis expressed in words is, "the proportion of all lung cancer deaths that are due to tobacco use isnothing 0.74." The null hypothesis is expressed symbolically as, "Upper H 0: pequals0.74."
Accepted Solution
A:
Answer:CStep-by-step explanation:The null hypothesis is the opposite of the alternative hypothesis. THe alternative hypothesis is the claim believed to be true. A report claims "that at most 74% of lung cancer deaths are due to tobacco use" so this is the alternative hypothesis. It's what is believed to be true. The null is the opposite that more than or at least 74% of lung cancer deaths are due to tobacco use. This is answer choice C.
