A curious student taking Math 119 at IVC decides to survey students at the college and compare rates of those who like English andthose who like Math. This student happens to like Math more, so they want to know if students feel the same way. Is there compellingstatistical evidence that the rate of students who prefer English is lower than the rate of students who prefer math?

The group stage is up for getting Gecko Socks if they also land between 25.5-32.1 hours on the wall on average. What prercent of the groups are expected to qualify for the socks?
We predict that children exhibit more aggressive act after watching a violent television show. The scores for ten children were recorded before they watched a violent show and then after they watched a violent show. Aggression was measured in terms of number of aggressive acts (e.g. hitting, yelling, kicking etc). Sample 1 (after TV show): 5,6,4,4,7,3,2,1,4,1 Sample 2 (before TV show): 4,6,3,2,4,1,0,0,5,2 What is the critical value?
