H0: p = 0.86
Ha: p < 0.86
One study claimed that 86%
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 236
college students and finds that 192
of them identify themselves as procrastinators. Does this evidence support the professor’s claim that fewer than 86%
of college students are procrastinators? Use a 0.05
level of significance.
