The type of polynomial that would best model the data is a <em>cubic</em> polynomial. (Correct choice: D)
<h3>What kind of polynomial does fit best to a set of points?</h3>
In this question we must find a kind of polynomial whose form offers the <em>best</em> approximation to the <em>point</em> set, that is, the least polynomial whose mean square error is reasonable.
In a graphing tool we notice that the <em>least</em> polynomial must be a <em>cubic</em> polynomial, as there is no enough symmetry between (10, 9.37) and (14, 8.79), and the points (6, 3.88), (8, 6.48) and (10, 9.37) exhibits a <em>pseudo-linear</em> behavior.

Answer:1.)49%
2.)5.3%
3)4.9%
4)46.1%
5)the events are independent of each other but not mutually exclusive.
6)4.9%
Step-by-step explanation:
From the data given
Event that a player in Npfl plays in his 30s is T
Event that a player plays in offense position is F
Drawing a set diagram
P(T) =10.2%
P(F)=48.6%
P(TnF)=4.9%
1.probability of T only or F only=10.2-4.9+48.6-4.9=49%
2.prob(Tonly)=prob(T)-Prob(PnT)
=10.2-4.9=5.3%
3.prob(TnF)=4.9%
4.Pr(TUF)'=100-{pr(Tonly)+Pr(Fonly)+P(TnF)}
100-(10.2-4.9+48.6-4.9+4.9)
100-(5.3+43.7+4.9)
=46 .1%
D.the two events are independent of each other i.e the occurrence of being in 30s and being an offensive players can happen simultaneously.
For thatsame reason ,they are NoT mutually exclusive.
E) prob (playing in 30s and being offensive) is p(TnF)=4.9%
