A security expert claims that at least 13% of all homeowners have a home security alarm. State H, and H, in words and in symbols. Then determine whether the hypothesis test for this claim isleft-tailed, right-tailed, or two-tailed. Explain your reasoning......State the null hypothesis in words and in symbols. Choose the correct answer below.O A. The null hypothesis expressed in words is, "the proportion of all homeowners who own a home security alarm is at most 0.13." The null hypothesis is expressed symbolically as, "Ho:ps0.13."O B. The null hypothesis expressed in words is, "the proportion of all homeowners who own a home security alarm is 0.13." The null hypothesis is expressed symbolically as, "Ho:p = 0.13."OC. The null hypothesis expressed in words is, "the proportion of all homeowners who own a home security alarm is at least 0.13." The null hypothesis is expressed symbolically as, "Ho:p20.13."O D. The null hypothesis expressed in words is, "the proportion of all homeowners who own a home security alarm is not 0.." The null hypothesis is expressed symbolically as, "Hg:p#0.13."

9.15 Toxic Mushrooms? Cadmium, a heavy metal, is toxic to ani- mals. Mushrooms, however, are able to absorb and accumulate cad- mium at high concentrations. The Czech and Slovak governments have set a safety limit for cadmium in dry vegetables at 0.5 part per million (ppm). M. Melgar et al. measured the cadmium levels in a random sample of the edible mushroom Boletus pinicola and pub- lished the results in the paper "Influence of Some Factors in Toxi- city and Accumulation of Cd from Edible Wild Macrofungi in NW Spain" (Journal of Environmental Science and Health, Vol. B33(4), pp. 439-455). A hypothesis test is to be performed to decide whether the mean cadmium level in Boletus pinicola mushrooms is greater than the government's recommended limit.
