One is the random condition. I'll write 'em up here. The random condition. And that would be that there's truly a random sample of games. And it tell us right here, he took a random sample of his 24 games. So we meet that condition. The second condition, when we're talking about chi-squared hypothesis testing, is the large counts.

Help the students to visualize this! When you do a confidence interval problem, shade the area that we believe the true parameter is in. Color the tails in a different color to make the students see the region a two-sided hypothesis test is assessing. Therefore - a 90% confidence interval would have 10% leftover in the tails - or 5% on each side.Lesson 6. 3 Practice.

ap stats chapter 9 test (section 9.2) what are the conditions for performing a significance test about a proportion? Random: The data must come from a well-designed random sample or randomized experiment; 10%: When sampling without replacement, check that n (10) ≤ N.; Large Counts: Both np0 and n (1-p0) are at least 10.
Success/Failure Condition: There should be at least 10 expected successes and 10 expected failures in a sample in order to use the normal distribution as an approximation. Written using notation, we must verify both of the following: Expected number of successes is at least 10: np ≥ 10. Expected number of failures is at least 10: n (1-p) ≥ 10.

The Large Counts Condition is satisfied when both np and n (1-p) are greater than or equal to 10, where n is the sample size and p is the probability of success. In other words, if the number of successes and failures in the sample is large enough, then we can assume that the distribution of the count of successes follows a normal distribution.The large counts condition can be expressed as np ≥ 10 and n (1-p) ≥ 10, where n is the sample size and p is the sample proportion. This means that both the number of successes (np) and the number of failures (n (1-p)) in the sample should be at least 10.The response does not satisfy component 3 because, although the response correctly names the test, the z-statistic formula provided is not correct.
