Explanation The fraction of trades in the sample and standard error was {1.338 and 0.039, respectnrelv. The 95% confidence interval for the population fraction calculated using CA3 is {0251, 0.415}. These interval values do not include 0.50- The null hypothesis can he stated as follows: Hg : Endowment Effect is Absent H1 : Endowment Effect is Present The tstatistics for the null hypothesis is as follows: _ [0.333 0.50} T [1.039 = 4.15 The absolute value of t-stats is greater than the 5% critical value which is 1.95. Thus, it is statisticallyr significant that there is no "erhzlovnnent e'ec This implies that the true traded fraction is 0.50. Veried Answer a 59% No. Yes
