Hypothesis Test 2 - Procrastinators One study (see https://brandongaille.com/17-lazy-procrastination-statistics/) claimed that 95% percent 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. Tips: The Central Limit Theorem for proportion states that (with the right conditions that we do have here) the sampling distribution of sample proportions is normal. We assume the 95% figure is correct, and use a standard deviation of 0.95*(1-0.95) 275 for the Hypothesis Test. So you need to find the probability that any (simple random) sample of 275 students will have a proportion of procrastinators less than the proportion in the given sample
