What is the alternate hypothesis? Thanks!

A study was conducted to investigate the effectiveness of hypnotism in reducing pain. A lower score indicates less pain. Results for randomly selected subjects are shown in the table below. Subject A B C D E IF G H Before 6.6 6.5 9.0 10.3 11.3 8.1 6.3 11.6 After 6.8 2.4 7.4 8.5 8.1 6.1 3.4 2.0 Are the pain measurements, on average, lower after hypnotism? Assuming the distribution of differences is normal, Use a Paired T-test and technology to answer the question at a 0.05 significance level. Use the after measurements as your first sample such that the mean of the differences is -3.13 and the standard deviation of the differences is 2.91. a) What is the alternate hypothesis?
