A candidate for mayor claims that under the

present administration, 45% of complaints about

city government are not addressed within two

weeks of submission. A watchdog citizens

group claims that the actual percentage is less

than 45%. The group conducted a SRS of 100

complaints submitted to the city government in

the last year and determined that only 40% of the

complaints were not addressed within two weeks

of submission. Do these data provide sufficient

evidence to reject the candidates claim at the

5% significance level?
