A concrete learner is a student who learns best when various types of hands-on manipulative activities are used to illustrate abstract concepts. Researchers have long believed that 60% of all students remain concrete learners until they are between 16 and 21 years of age. Each student in a random sample of 32 students age 17 to 19 was evaluated, and it was found that 24 of the 32 were concrete learners. Would it be appropriate to use the z-test for a population proportion to test to determine if the proportion of concrete learners in this age group is less than 0.60
