5. One study claimed that a whopping 95% of college students identify themselves as

procrastinators. Since the report also claims that only 20% of the general population claim to be procrastinators, one professor believes that the claim regarding college students is too high. The professor conducts a simple random sample of 275 college students and finds that 251 of them identify themselves as procrastinators. Does this evidence support the professor's claim that fewer than 95% of college students are procrastinators? Use a 0.10 level of significance. a) State the null and alternative hypotheses. b) Determine the distribution to use for the test statistic, and state the level of significance. c) Calculate the test statistic. d) Draw a conclusion using the rejection region method. Using the given level of significance, write a conclusion of the decision.
