Do lizards play a role in spreading plant seeds? Some research carried out in a country would suggest so. The researchers collected 400 seeds of this particular type of fig, 100 of which were from each treatment: lizard dung, bird dung, rock hyrax dung, and uneaten figs. They planted these seeds in batches of 5, and for each
group of 5 they recorded how many of the seeds germinated. This resulted in 20 observations for each treatment. The treatment meens and standard deviations are given in the accompanying table.

Does the interval provide evidence that seeds eaten and then excreted by lizards germinate at a higher rate, on average, than those eaten and then excreted by birds?
O Since both endpoints of the interval are positive, we do not have convincing evidence that seeds eaten and then excreted by lizards germinate at a higher rate from those eaten and then excreted by birds.
O Since both endpoints of the interval are positive, we have convincing evidence that seeds eaten and then excreted by lizards germinate at a higher rate from those eaten and then excreted by birds.
