A university officer wants to know the proportion of registered students that spend more than 20 minutes to get to school. He selects two parking decks at the university and talked with students at those decks. Of 25 students found in the decks, 12 have a commute under 20 minutes and 13 have a commute more than 20 minutes.
Select one: THIS IS A MULTIPLE CHOICE QUESTION
a. Yes.
b. No, because it wasn't a random sample.
c. No, because n(p-hat) < 10 or n(q-hat) < 10.
d. No, because the sample size wasn’t at least 30 and the population wasn’t normally distributed.
e. No, because we already know the population proportion.
THE ANSWER IS NOT A) YES.
i dont understand the confusion on this question. it is just a multiple choice question. but i know for a fact that A is not the correct answer because i put A on attempt number 1 of 2 attempts.
