Question

A security expert claims that at least 13% of all homeowners have a home security alarm, State Ho and H, 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. O A. The null hypothesis expressed in words is, "the proportion of all homeowners who own a home security alarm is not 0.13." The null hypothesis is expressed symbolically as, "Ho:p*0.13. B. 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." C. 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: p0.13." OD. 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: P0.13." 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 0.13." The alternative hypothesis is expressed symbolically as, "H: p=0.13." OB. The alternative hypothesis expressed in words is, "the proportion of all homeowners who own a home security alarm is not equal to 0.13." The alternative hypothesis is expressed symbolically as, "H:p*0.13." OC. The alternative hypothesis expressed in words is, "the proportion of all homeowners who own a home security alarm is more than 0.13." The alternative hypothesis is expressed symbolically as, "H:p>0.13." OD. The alternative hypothesis expressed in words is, "the proportion of all homeowners who own a home security alarm is less than 0.13." The alternative

Answer 1

1).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, " H₀ : p $\geq$ 0.13 " (B)

2). The alternative hypothesis expressed in words is, "the proportion of all homeowners who own a home security alarm is less than 0.13." The alternative is expressed symbolically as, " H₀ : p < 0.13" (D)
