1. A. Yes, this is a probability density function because F(x) are non-negative for each outcome
and the sum of F(x) is one.

Problem Set 4
1. A. (0 + 1) 0 = 1 (12.52 + 2.12) 12.52 = 2.12
B. H0 : 1 = 0 v.s H1 : 1 0
T = 2.12/0.36 = 5.89 Pr(Z>5.89) p-value < 0.0001
From this very small p-value, we would reject the null hypothe
Problem Set 6
1. A. H0: 1> 0 v.s. H1: 1< 0
T = (5.46 0)/0.21 = 26 From the t-statistic I can conclude that we cant reject the null
hypothesis because the t-statistic is greater than zero.
