t=292.958大于0，拒绝原假设，所以b1不等于1，应该是平稳的啊。

问题如下：

DeMolay's statement that the coefficients depicted in Exhibit 1 are consistent with a random walk is most likely:

选项：

A.incorrect because b1 should be close to 0. B.incorrect because b0 should be close to 1. C.correct.

解释：

When modeled using a AR(1) model, as in the formula given in Exhibit 1, random walks will have an estimated intercept coefficient near zero and an estimated slope coefficient on the first lag near 1. Therefore, his statement is correct.
