With reference to Exercise 10.1, what can we say with \(95 \%\) confidence about the maximum error if we use the sample proportion as an estimate of the true proportion of complaints filed against this construction company where the proportion of sand exceeds 75 percent?

Data From Exercise 10.1

10.1 In a random sample of 150 complaints filed against a construction company for mixing excess sand in their concrete mixture, 95 complaints showed that the pro- portion of sand in the mix exceeded 75 percent. Con- struct a 90% confidence interval for the true proportion of complaints filed against this construction company where the proportion of sand exceeded 75 percent, us- ing the large sample confidence interval formula.
