Fred collects data from two populations. Maria uses those data to construct a (two-sided) 90% confidence interval

Question:

Fred collects data from two populations. Maria uses those data to construct a (two-sided) 90% confidence interval for μ1, - μ2, and gets (-3.4,23.7). At the same time Sam uses the data to test H0: μ1 = μ2 versus HA: μ1 > μ2 (which he chose to test before seeing the data) with α = 0.05. Does Sam reject H0? Or can we not tell from the information given? Explain your reasoning.
