The alternative hypothesis should state the difference or relationship between the two populations being compared. Both choices a and c correctly state the alternative hypothesis in terms of population means and direction of the difference (i.e., bird-watching intervention mean is greater than non-bird-watching control group mean). Choice b is incorrect because it refers to sample means instead of population means.
