The conditions are Random and Large Counts. The large counts condition is different than the one we use for proportions: the expected counts must be greater than 5.

There are $\frac{205}{250}$ well-prepared students and $\frac{137}{250}$ poorly prepared students who answered a certain item in the exam correctly.2. Independence: The sample values must be independent of each other. 3.

Each observation in the sample data should be independent of every other observation. This means that no two observations in a sample are related to each other or affect each other in any way. If you use a random sampling method to collect the data, this assumption is typically met. mudae kakera cheatolenka peruvian bistro boca raton 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.
