Perform the indicated sign test. Be sure to do the following: Identify the claim mathematically and state the null and
alternative hypotheses. Determine the critical value and find the test statistic. Decide whether to reject or fail to reject
the null hypothesis and interpret the decision in the context of the original claim.
-A college researcher claims that the median time worked by full time students is at least 10 hours per week. In
a random sample of 100 students, 59 worked more than 10 hours, 10 worked exactly 10 hours and the rest
worked less than 10 hours. Test the researcherʹs claim. Use $$\alpha = 0.05$$
