The large counts condition is that the expected value of each observed category should be at least 5. Expected values of each age group can be found by multiplying the percentage found in the 2016 study by the sample size in the sample June took.The three conditions for calculating a hypothesis test for the population proportion p p p are: Random, Independent (10% condition), Normal (large counts). Random: Satisfied, because the sample is a random sample.When the Random 10% Large Counts Condition are met for a binomial distribution, we can expect that the sampling distribution of the sample proportion π-hat to be approximately normally distributed due to the Central Limit Theorem.
