State the appropriate null hypothesis H0 and alternative hypothesis HA in each of the following cases. a. The student in a large first year biology class attend lecture altogether but are divided into smaller groups which meet in recitation sections, some in the morning, some in the afternoon, and some in the evening. Historically the average on the first exam given to the lecture class each semester has been 72. The professor thinks that students who attend morning recitation sections will have a higher mean score than other students. b. A university gives credit in Italian language courses to students who pass a written placement test. The language department wants to know if students who get credit in this way differ in their understanding of spoken Italian from students who actually take the French courses. Experience has shown that the mean score of students in the courses on a standard listening test is 26. The language department gives the same listening test to a sample of 35 students who passed the credit examination to see if their performance is different.
