Men hoping to have children are encouraged to avoid hot tubs or saunas because heating the scrotum by just 1 degree Celcius can reduce sperm count and sperm quality. A new study indicates that men might want to also avoid using a laptop computer on their lap for long periods of time. In the study, 29 men sat with a laptop for an hour in their lap. Mean temperature increase and sample standard deviation of the data from 29 men were respectively. The study wanted to test the following hypothesis: x(bar)=2.31 degrees Celcius and s=0.96 degrees Celcius Ho:u=1 vs Ha:u>1 at a=5% a)Test the hypothesis about the mean temperature increase (this includes finding the test statistics, p-value, and drawing conclusion)
