2. The market demand schedule for tongs is Q = 100 – P; the market supply schedule is Q = -50 + 2P. Calculate:

3. Research on NHL player salaries has yielded the following regression model, where
SALARY = player’s base contract salary
in $thousands
YRS = number of years in NHL
PTS = goals plus assists in prior season
PNLTY = total minutes of game penalties
assessed in prior season
PNLTYSQ = total penalty minutes in prior
season squared
Coefficient t-statistics are reported in square brackets.
SALARY = 105.4 + 42.6 (YRS) + 6.6 (PTS) + 4.1 (PNLTY) - 0.026 (PNLTYSQ)
[3.66] [1.05] [2.41] [4.60] [-2.07]
N = 244 players R-Square = 68.6
Which model coefficients are NOT significantly different from zero at
the 90% confidence level?
According to this model, what is the salary-maximizing level of penalty
minutes, ceteris paribus?
