Consider observations of the number of wins per season by
National Football League teams over the years 1989-2008. The
observed mean is 8 wins/season and the observed standard deviation
is 3.02. A histogram illustrates these data.
Referring to these NFL data and assuming normality, the
probability that a randomly chosen team wins 11 or more games
is?

Home vs Road Wins – Significance Test: For the
NHL regular season, the Chicago Blackhawks won 26 out of 41 home
games and won 18 out of 41 away games. Clearly the Blackhawks won a
greater proportion of home games. Here we investigate whether or
not they did significantly better at home than on
the road. The table summarizes the relevant data. The p̂'s
are actually population proportions but you should treat them as
sample proportions. The standard error (SE)...
