One study claimed that 91%
of college students identify themselves as procrastinators. A professor believes that the claim regarding college students is too high. The professor conducts a simple random sample of 244
college students and finds that 215
of them identify themselves as procrastinators. Does this evidence support the professor’s claim that fewer than 91%
of college students are procrastinators? Use a 0.10
level of significance.
