    - The required sample size for the interval estimation of the population mean μ can be computed if we specify the population standard deviation σ, the value of zα/2zα/2based on the confidence level 100(1 − α)% and the desired margin of error E. A) True B) False - In stratified random sampling, the population is first divided up into mutually exclusive and collectively exhaustive groups, called strata. Then simple random samples are drawn from each stratum, which are proportional to...

    A random sample of size 90 is selected from a population of over 2,000 students. The sample is measured on an achievement test and the mean score on the test is 79.5. The difference between the sample mean and the population mean is due to: sampling bias sampling error the sampling fraction sampling stratification Sampling bias is variation caused by random fluctuation.

    Which of the following is true about the sampling distribution of means? Shape of the sampling distribution of means is always the same shape as the population distribution, no matter what the sample size is. Sampling distribution of the mean is always right skewed since means cannot be smaller than 0. Sampling distributions of means are always nearly normal. Sampling distributions of means get closer to normality as the sample size increases.
