Three experiments investigating the relation between need for cognitive closure and persuasion were performed. Part of the study involved administering a "need for closure scale" to a group of students enrolled in an introductory psychology course. The "need for closure scale" has scores ranging from 101 to 201. For the 77 students in the highest quartile of the distribution, the mean score was x = 175.10. Assume a population standard deviation of a = 7.83. These students were all classified as high on high on their need for closure. Find a 95% confidence interval for the population mean score u on the "need for closure scale" for all their need for closure. Assume that the 77 students represent a random sample of all students who are classified students with a high need for closure. (Round your answers to two decimal places.) lower limit upper limit
