Most people can roll their tongues, but many people can’t. whether or not a person can roll his tongue is genetically determined. suppose we are interested in determining what fraction of students can roll their tongues. a recent news article claimed that 75% of people can roll their tongues, whereas others claim that the percentage is not 75%. we get a simple random sample of 400 students and find that 317 can roll their tongues. is this significant evidence that the percent of students that can roll their tongues is different from 75%? carry out the appropriate hypothesis test. be sure to write down the null and alternative hypotheses, find the test statistic and the p-value, and state your conclusions.
