Question
An actuary analyzes a company’s annual personal auto claims, M and annual commercial
auto claims, N . The analysis reveals that V ar(M ) = 1600, V ar(N ) = 900, and the
correlation between M and N is ρ = 0.64. Compute V ar(M + N ).

The model specifies that sales S vary jointly with disposable personal income Y and the population between ages 15 and 40, Z, and inversely with the price of the snowmobiles P. Based on past data, the best estimate of this relationship is S=kYZP where k has been estimated (with past data) to equal 100. If Y=11,000,Z=1,200, and P=20,000, what value would you predict for S? What happens if P is reduced to $17,500? How would you go about developing a value for k? What are the potential weaknesses of this model?arrow_forward
