| B. |
The rejection region for level α test is z ≤ zα if the test is an upper-tailed test. |
|
| C. |
The rejection region for level α test is z ≥ zα if the test is an upper-tailed test. |
|
| D. |
The rejection region for level test is either z ≥ zα/2 or z ≤ zα if the test is a two-tailed test. |

We are designing an experiment to test the following set of hypotheses about a population mean: H0:μ≥40 versus H1:μ<40. If the true population mean was 38, what sample size would we need in order to achieve a power of 0.8, with α=2.5%? Assume a standard deviation of 8 .

A random sample of n - 16 scores is selecdted from a normal population with a mean of p - 50. After atreatment is administered to the individuals in the sample, the sample mean is found to be M -54 If the population standard deviation is σ-8, is the sample mean sufficient to conclude that the treatment has a significant effect?

- 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...
