A security expert claims that exactly 18% of all homeowners have a home security alarm. State Ho and H₂ 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. OA. The null hypothesis expressed in words is, "the proportion of all homeowners who own a home security alarm is 0.18." The null hypothesis is expressed symbolically as, "Ho: P=0.18." OB. The null hypothesis expressed in words is, "the proportion of all homeowners who own a home security alarm is at most 0.18." The null hypothesis is expressed symbolically as, "Ho: p≤0.18." OC. The null hypothesis expressed in words is, "the proportion of all homeowners who own a home security alarm is more than 0.18." The null hypothesis is expressed symbolically as, "Ho: p>0.18." O D. The null hypothesis expressed in words is, "the proportion of all homeowners who own a home security alarm is at least 0.18." The null hypothesis is expressed symbolically as, "Ho: p20.18." 4 State the alternative hypothesis in words and in symbols. Choose the correct answer below. OA. The alternative hypothesis expressed in words is, "the proportion of all homeowners who own a home security alarm is 0.18." The alternative hypothesis is expressed symbolically as, "H₂: p=0.18." ... OB. The alternative hypothesis expressed in words is, "the proportion of all homeowners who own a home security alarm is more than 0.18." The alternative hypothesis is expressed symbolically as, "Ha: p>0.18." OC. The alternative hypothesis expressed in words is, "the proportion of all homeowners who own a home security alarm is less than 0.18." The alternative hypothesis is expressed symbolically as, "Ha: p <0.18." OD. The alternative hypothesis expressed in words is, "the proportion of all homeowners who own a home security alarm is not equal to 0.18." The alternative hypothesis is expressed symbolically as, "Ha: p *0.18." The hypothesis test is because the contains ▼
