Over the past several years, the proportion of one-person households has been increasing. The Census Bureau would like to test the hypothesis that the proportion of one-person households exceeds 0.27. A random sample of 125 households found that 43 consisted of one person. To conduct the hypothesis test, what distribution would you use to calculate the critical value and the p-value?

a. the Student's t-distribution with 124 degrees of freedom
b. the Student's t-distribution with 125 degrees of freedom
c. the standard normal distribution
d. the Student's t-distribution with 42 degrees of freedom
