Large counts condition ap stats

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.

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.AP Stat Exam reminders (Sampling Distributions and Confidence Intervals) 10 terms. eboswell6.

The value of the chi-square test statistic was χ2=7.82 with a corresponding p-value of 0.02. So our large counts condition would change to 0.55(85) ≥ 10 & 0.45(85) ≥ 10, which still holds for this particular problem. In other words, when we are given an actual p to check this condition, use it.
