The humane society selected a random sample of households in its county and used the sample to estimate the proportion of all households that own at least one dog. The conditions for calculating a 95 percent confidence interval for the proportion of households in this county that own at least one dog were checked and verified, and the resulting confidence interval was 0.451 ± 0.091. Construct and interpret the 95 percent confidence level in this context. How many households were selected in the humane society’s sample? Show how you obtained your answer.
