Answer: they can conclude the distributions are different at the 95% confidence interval. Compute the z test statistic to solve this.

Step-by-step explanation: to get the 95% confidence interval on the mean take the mean value (984) +/- (2*standard deviation divided by the square root of the number of samples) (I.e. 984 +/- (2*267/sqrt(501)))
