Large counts condition ap stats.

The shape of a sampling distribution of p ^ 1 − p ^ 2 ‍ depends on whether both samples pass the large counts condition. If we expect at least 10 ‍ successes and at least 10 ‍ failures in both samples, then the sampling distribution of p ^ 1 − p ^ 2 ‍ will be approximately normal.

50 (0.6)=30. Now look, we can take the number of successes/ failures to find the proportion of successes/failures in the sample: 20/50= 0.4. 0.4=p. 30/50=0.6. 0.6= 1-p. So essentially, we need to first check that the sample size is larger than 30. And if that is met, then we check if the number of successes/ failures in a sample are more than 10.Later in the course, we take these dotplots and approximate them with normal distributions by checking the Large Counts or the Large Sample/Normal conditions. ...
