A researcher is interested in the proportion of children that prefer specific types of candy. It was originally believed that 34% of children prefer Reeses, 21% prefer Hersheys, 20% prefer Gummy Bears, and 25% SweetTarts. The researcher believes the proportions have changed, and thus the researcher takes a random sample of 500 children and finds that 36% of them prefer Reeses, 19% of them prefer Hersheys, 18% of them prefer Gummy Bears, and 27% of them prefer sweet tarts. At the 5% significance level, what conclusion can be reached? What is the rejection region for this test?
