Large counts condition ap stats.
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. 🧢
The Large Sample Condition: The sample size is at least 30. Note: In some textbooks, a "large enough" sample size is defined as at least 40 but the number 30 is more commonly used. When this condition is met, it can be assumed that the sampling distribution of the sample mean is approximately normal. This assumption allows us to use samples ...10% condition. check that 1/10 of N1 is greater than or equal to n1. check that 1/10 of N2 is greater than or equal to n2. normal/large counts condition. make sure that n1 and n2 are both greater than or equal to 30. if the sample size is less than 30, graph both sets of data and check for skewedness and outliers. confidence interval equation.The Large Counts conditions says that all expected counts must be at least 5 Conditions for performing a chi-square test for goodness of fit 1) Random: The data come from a well-designed random sample or randomized experiment 10%: When sampling without replacement, check that n is less than or equal to 1/10 N 2) Large Counts: All expected ...State appropriate hypotheses and compute the expected counts and chi-square test statistic for a chi-square test for goodness of fit.

Random Sample - The data are a random sample from the population of interest. 10% Rule - The sample size is no more than 10% of the population size: ≤. 10. Large Counts/Normality - If the sample size is large ( ≥ 30), then we can assume normality for any shape of distribution.
