AP ® STATISTICS 2013 SCORING COMMENTARY at the correct value of the requested standard deviation, which satisfies the third component. Because each of the three components was satisfied, part (b-ii) was as scored essentially correct. Because two parts50 (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.

The conditions we need for inference on one proportion are: Random: The data needs to come from a random sample or randomized experiment. Normal: The sampling distribution of p ^. . needs to be approximately normal — needs at least 10. . expected successes and 10. . expected failures.Study with Quizlet and memorize flashcards containing terms like one sample z interval, two sample z interval, one sample t interval and more.Confirm that the sample is large enough to assume that the sample proportion is normally distributed. Use \(p=0.90\), corresponding to the assumption that the retailer's claim is valid. Assuming the retailer's claim is true, find the probability that a sample of size \(121\) would produce a sample proportion so low as was observed in this ...50 (0.6)=30.

If a response is between two scores (for example, 2 1⁄2 points), use a holistic approach to decide whether to score up or down, depending on the strength of the response and quality of the communication.Start studying AP Stats Test.
