PS.19The student will identify the meaning of sampling distribution with reference to random variable, sampling statistic, and parameter and explain the Central Limit Theorem. This will include sampling distribution of a sample proportion, a sample mean, a difference between two sample proportions, and a difference between two sample means.

or . The intervals are fairly similar, which is why we choose to approximate the sampling distribution of with a z distribution when . 10.18 The degrees of freedom for s2, the pooled estimator of are . a b c 10.19 a b 10.20 When the actual data are given and s2 must be calculated, the calculation is done by

Use your calculator to help evaluate a binomial probability. If X is B(n, p), find µx and (x (that is, calculate the mean and variance of a binomial distribution). Use a Normal approximation for a binomial distribution to solve questions involving binomial probability.

p) Suppose sample of size=62 from some large population has =12 and s=12, we can use t-interval procedure for the confidence interval for the population mean even if population has left skewed distribution. True False. q) Suppose probability of you passing this test is 0.75, then probability of you failing it is 25%. True False

Topic 16. Sampling Distributions 1: Proportions. Overview. You have been studying probability and probability distributions.These ideas arise in the practice of statistics because sound data collection strategies involve the deliberate introduction of randomness.. Therefore, drawing meaningful conclusions from sample data requires an understanding of properties of randomness.

C. The sampling distribution of a statistic is the distribution of values taken by the statistic in . all possible samples of the same size from the same population. The mean of the . sampling distribution of is the population mean. A. Since the P-value is a probability, so it must be between 0 and 1. B. For 95% confidence, z = 1.96.

When the sample size n is large, the sampling distribution of is approximately Normal. What test can you use to determine if the sample is large enough to assume that the sampling distribution is approximately normal? 7.3 Sample Means (pp.442-452) 1. What are the mean and standard deviation of the sampling distribution of the sample mean ?
