The significance level is alphaequals0.05. Choose the one-proportion z-test, and check the conditions. Note that the sample is random and the observations are independent. Next check the Large Sample Size condition. The expected numbers of successes and failures are np 0equals906 times0.54 equals about 489, which is more than 10, and n(1minus0.54)equalsabout nothing, which is more than nothing. The population size is more than 10 times 906.
