If a school secretary copies 168 math worksheets for a class of 28 students, how many math worksheets must be prepared for a class of 32 students?

How many outfits can be made with three tops, nine pants, and two jackets?

Would appreciate the help, thanks!

After the rule change between 2006 and 2007 that permitted teams to prepare their own footballs, new fumble statistics were accumulated for the 8 years from 2007 thru 2014. Once again, the average fumbles per touch for each of 23 teams during this time period are given below: The numbers are the actual numbers. They are not just invented for this assignment. 36,38,40,40,44,44,44,44,46,46,46,46,48,48,48,48,50,50,50,52,52,56,74. During the 2007-2014 period, the New England Patriots fumbled the ball one time for every 74 touches. Conduct a z-test that tests whether it is reasonable to think that the Patriots had no particular competitive advantage on fumbling during the time period 2007-2014.
