A security expert claims that exactly 15% of all homeowners have a home security alarm. State Ho and Ha 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. ... O C. The null hypothesis expressed in words is, "the proportion of all homeowners who own a home security alarm is more than 0.15." The null hypothesis is expressed symbolically as, "Ho: p>0.15." O D. The null hypothesis expressed in words is, "the proportion of all homeowners who own a home security alarm is at least 0.15." The null hypothesis is expressed symbolically as, "Ho:p20.15." State the alternative hypothesis in words and in symbols. Choose the correct answer below. O A. The alternative hypothesis expressed in words is, "the proportion of all homeowners who own a home security alarm is more than 0.15." The alternative hypothesis is expressed symbolically as, "Ha: p>0.15." O B. The alternative hypothesis expressed in words is, "the proportion of all homeowners who own a home security alarm is not equal to 0.15." The alternative hypothesis is expressed symbolically as, "Ha: p#0.15." OC. The alternative hypothesis expressed in words is, "the proportion of all homeowners who own a home security alarm is 0.15." The alternative hypothesis is expressed symbolically as, "Ha: p = 0.15." O D. The alternative hypothesis expressed in words is, "the proportion of all homeowners who own a home security alarm is less than 0.15." The alternative hypothesis is expressed symbolically as. "Ha: p<0.15."

Transcribed Image Text:A security expert claims that exactly 15% 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.
C. The null hypothesis expressed in words is, "the proportion of all homeowners who own a home security alarm is more than 0.15." The null hypothesis is
expressed symbolically as, "Ho: p > 0.15."
D. The null hypothesis expressed in words is, "the proportion of all homeowners who own a home security alarm is at least 0.15." The null hypothesis is
expressed symbolically as, "Ho: p20.15."
State the alternative hypothesis in words and in symbols. Choose the correct answer below.
A. The alternative hypothesis expressed in words is, "the proportion of all homeowners who own a home security alarm is more than 0.15." The alternative
hypothesis is expressed symbolically as, "Ha: p> 0.15."
B. The alternative hypothesis expressed in words is, "the proportion of all homeowners who own a home security alarm is not equal to 0.15." The alternative
hypothesis is expressed symbolically as, "Ha: p +0.15."
C. The alternative hypothesis expressed in words is, "the proportion of all homeowners who own a home security alarm is 0.15." The alternative hypothesis is
expressed symbolically as, "H2: p = 0.15."
O D. The alternative hypothesis expressed in words is, "the proportion of all homeowners who own a home security alarm is less than 0.15." The alternative
