Plain-text version

Consider the uniform distribution over the interval [a,b]. Then (A) the mean depends on the length of the interval, but the variance does not (B) the mean does not depend on the length of the interval, but the variance does (C) neither the mean nor the variance depends on the length of the interval (D) the mean and the variance both depend on the length of the interval
