conception: for the null hypothesis test problem why we can use standard normal distribution table? by the central limited theorem and law of large number we have that when n is getting large, then the sample distribution will be normal distribution but it doesn't mean it is standard normal distribution. But why we can still use the table to find the value

The Normal Probability Distribution In §6.2 we are introduced to the Normal Probability Distribution and the special case of the Normal Probability Distribution, the Standard Normal Probability Distribution, which is a Normal Probability Distribution with mean (u) zero and variance (σ2) one (and standard deviation of 1). What is a z score? 2. What is the purpose of a z score? 3. If a z score were -3, where on the graph would it be? Is this a rare or...

Open the Excel program Suppose we want to know the standard normal distribution up to the given value. That is P(Z < a). Lets use Excel instead of the standard normal distribution table In cell A1 type mean. In cell B1 type 0. That means that we are letting mean be zero. click on cell A2 and type SD. In cell B2 type 1. That means that we are letting standard deviation be one. That is, the normal distribution is...
