The 10% condition typically refers to the current population size from which the sample is drawn, rather than considering future populations. In your scenario, if you're analyzing data from all 29 kids in your senior class, and that represents more than 10% of the current seniors at your school but less than 10% of all seniors who will ever attend your school, it would still qualify for the 10 ...

Before you can use a sampling distribution for sample proportions to make inferences about a population proportion, you need to check that the sample meets certain conditions. One of these conditions is the large counts condition, which states that the sample size should be large enough for the distribution of the sample ...The Large Counts Condition We will use the normal approximation to the sampling distribution of for values of n and p that satisfy np 10 and np(1 ) 10 . 7.3 - Sample Means is the mean of a sample from a large and standard deviation .

Our sample size here n is equal to 125 and our population proportion of the proportion of children that are reached each week by radio is 88% so p is 0.88. So now let's calculate np so n is 125 times p is 0.88 and is this going to be greater than or equal to 10.

For any Proportion Inference, you must check Large Counts to confirm normality. You can only check Central Limit Theorem for Quantitative Data (Means)..
