Large counts condition ap stats.
In the video, we see that the Normal approximation for the binomial distribution works best when: The sample size (n) is larger. The probability of success (p) is closer to 0.5. We combine these two ideas to come up with the Large Counts condition, which says that the expected number of successes and expected number of failures are both at ...

A total of 33 tomato plants were grown; 16 using fertilizer A, and 17 using fertilizer B. The distributions of the data did not show marked skewness and there were no outliers in either data set.

The follow-up analysis is not required for full credit when performing the test, but the thinking involved in the follow-up analysis may help students succeed in part (b) of the question. See 2008 #5 and 2016 #2.The conditions we need for inference on a mean are: Random: A random sample or randomized experiment should be used to obtain the data. Normal: The sampling distribution of x ¯. . (the sample mean) needs to be approximately normal. This is true if our parent population is normal or if our sample is reasonably large ( n ≥ 30) .

When calculating critical values from Table A, students will mistakenly look for the wrong area. For example, when finding the critical value for an 80% confidence interval, naturally students want to look for an area of 0.80. But we know that Table A gives the area to the left of a specific z-score, which includes the 10% area in the left tail. 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. When we aren't given a p-value, use the next best thing by using your p-hat. 🧢
