Question

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.
Step 3 of 3: Draw a conclusion and interpret the decision.

We reject the null hypothesis and conclude that there is insufficient evidence at a 0.05 level of significance that fewer than 86 % of college students are procrastinators. The sample data supports the claim that a high percentage of college students identify themselves as procrastinators, as 192 out of 236 students in the sample identified themselves as such.
