Fresh features from the #1 AI-enhanced learning platform. Explore the lineupThe 10% condition states that sample sizes should be no more than 10% of the population. Whenever samples are involved in statistics, check the condition to ensure you have sound results. Some statisticians argue that a 5% condition is better than 10% if you want to use a standard normal model. For example, the 10% condition normally applies ...The z-test is a statistical test for comparing the proportions from two populations. It can be used when the samples are independent, n1ˆp1 ≥ 10, n1ˆq1 ≥ 10, n2ˆp2 ≥ 10, and n2ˆq2 ≥ 10. The formula for the z-test statistic is: z = (ˆp1 − ˆp2) − (p1 − p2) √(ˆp ⋅ ˆq( 1 n1 + 1 n2))

A simulation based estimate of the P-value (seriously 2009B #5 is the best question ever….if your students do well on this question, then you did a great job teaching Chapter 9!)The standard deviation of the difference is: σ p ^ 1 − p ^ 2 = p 1 ( 1 − p 1) n 1 + p 2 ( 1 − p 2) n 2. (where n 1 and n 2 are the sizes of each sample). This standard deviation formula is exactly correct as long as we have: Independent observations between the two samples.

🎥 Watch: AP Stats - Normal Distributions. A z-score indicates how many standard deviations above or below the mean a piece of data is. If a z-score is -2, it is 2 standard deviations below the mean. If a z-score is 1, it is 1 standard deviation above the mean. When asked to interpret a z-score, it is imperative that you indicate the ...

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.
