A study selected independent random samples of 50 dogs and 60 cats and found that 38 of the dogs and 15 of the cats could be trained to fetch a ball. Do these data provide convincing evidence that the proportion of all dogs that can be trained to fetch a ball is greater than the proportion of all cats that can be trained to fetch a ball?

Use Alpha = 0.05.

Select all statements that are correct.

We have two independent random samples.
We have two groups in a randomized comparative experiment.
The 10% condition is met.
The 10% condition does not apply.
The expected number of successes and failures for both samples are 38, 12, 15, 45.
The expected number of successes and failures for both samples are 24, 26, 29, 31.
