State Ho and H₂ in words and in symbols. Then determine whether the hypothesis test is left-tailed, right-tailed, or two-tailed. Explain your reasoning. Sketch a normal sampling distribution and shade the area for the P-value. A security expert claims that more than 12% of all homeowners have a home security alarm. State the null hypothesis in words and in symbols. Choose the correct answer. OA. The null hypothesis expressed in words is, "the proportion of all homeowners who own a home security alarm is not 0.12." The null hypothesis is expressed symbolically as, "Ho: p*0.12." OB. The null hypothesis expressed in words is, "the proportion of all homeowners who own a home security alarm is 0.12." The null hypothesis is expressed symbolically as, "Ho: p=0.12." OC. The null hypothesis expressed in words is, "the proportion of all homeowners who own a home security alarm is at most 0.12." The null hypothesis is expressed symbolically as, "Ho: p≤0.12." OD. The null hypothesis expressed in words is, "the proportion of all homeowners who own a home security alarm is at least 0.12." The null hypothesis is expressed symbolically as, "Ho: p20.12." State the alternative hypothesis in words and in symbols. Choose the correct answer. OA. The alternative hypothesis expressed in words is, "the proportion of all homeowners who own a home security alarm is more than 0.12." The alternative hypothesis is expressed symbolically as, "H₂: p>0.12." OB. The alternative hypothesis expressed in words is, "the proportion of all homeowners who own a home security alarm is 0.12." The alternative hypothesis is expressed symbolically as, "H₂: p=0.12." OC. The alternative hypothesis expressed in words is, "the proportion of all homeowners who own a home security alarm is less than 0.12." The alternative hypothesis is expressed symbolically as, "Ha: p<0.12." OD. The alternative hypothesis expressed in words is, "the proportion of all homeowners who own a home security alarm is not equal to 0.12." The alternative hypothesis is expressed symbolically as, "H₂: p*0.12." The hypothesis test is because the contains ▼ Sketch a normal sampling distribution and shade the area for the P-value.
