.....students solve the following questions....

1) The average KPSS score of students graduating from University A is 68. This year, randomly, 24 students were chosen among the graduates, and the average scores of these students were 72; standard deviations were found to be 10. Is there a significant difference between the KPSS scores of the students who graduated in the previous years and the average scores of the students who graduated this year? Solve the question using all 6 steps of the hypothesis test.

2) A teacher asks them to attend online classes by contacting their students and talking about them. However, when it comes to attending classes, only 40% of those who promised to attend attended. If this teacher contacts 100 people, what would be the probability of attending 45 to 50 lessons as a result?
