The Survey of Study Habits and Attitudes SSHA is a psycholog

The Survey of Study Habits and Attitudes (SSHA) is a psychological test that measures students’ study habits and attitude toward school. The survey yields several scores, one of which measures student attitudes toward studying. The mean student attitude score for college students is about 50, and the standard deviation is about 15. A researcher in the Philippines is concerned about the declining performance of college graduates on professional licensure and board exams. She suspects that poor attitudes of students are partly responsible for the decline and that the mean for college seniors who plan to take professional licensure or board exams is less than 50. She gives the SSHA to an SRS of 225 college seniors in the Philippines who plan to take professional licensure or board exams. Suppose we know that the student attitude scores in the population of such students are Normally distributed with standard deviation = 15.

State the null and alternative hypotheses for the study of college seniors\' attitudes in the Philippines.

Solution

This is the sentence that you have to read more carefully because that is your hypothesis

A researcher in the Philippines is concerned about the declining performance of college graduates on professional licensure and board exams. She suspects that poor attitudes of students are partly responsible for the decline and that the mean for college seniors who plan to take professional licensure or board exams is less than 50

so the answer is

because the alternative hypothesis will never have a equal sign
