The explanation of the first example states that "A conditional distribution turns each count in the table into a percentage of individuals who fit a specific value of one of the variables.", but in the exercise the values aren't always percentages; just counts!The conditions we need for inference on one proportion are: Random: The data needs to come from a random sample or randomized experiment.

DF (GOF) n -1 (n = number of categories) X^2cdfEach essentially correct (E) part counts as 1 point, and each partially correct (P) part counts as 1⁄2 point. If a response is between two scores (for example, 2 1⁄2 points), use a holistic approach to decide whether to score up or down, depending on the strength of the response and quality of the communication. This idea becomes the critical value for a confidence interval. In Chapter 4, students learned that the purpose of a random sample is so that we can generalize to the larger population. In this chapter, this idea becomes the Random condition for inference. In Chapter 6, students learned to check the 10% condition in the binomial setting to be ...

It can be used when the samples are independent, n1ˆp1 ≥ 10, n1ˆq1 ≥ 10, n2ˆp2 ≥ 10, and n2ˆq2 ≥ 10. The formula for the z-test statistic is: z = (ˆp1 − ˆp2) − (p1 − p2) √(ˆp ⋅ ˆq( 1 n1 + 1 n2)) dmv kiosk rancho cucamonga The 10% Condition says that our sample size should be less than or equal to 10% of the population size in order to safely make the assumption that a set of Bernoulli trials is independent. Of course, it's best if our sample size is much less than 10% of the population size so that our inferences about the population are as accurate as possible.AP Stats sampling distributions.
