Question

Suppose you are planning to collect a set of data in an experiment where you expect the original population mean to be 10 with a standard deviation of 3. Your initial plan is to collect 20 observations, and you expect your experimental manipulation to increase the mean of your observations by 1. You plan to test with α=0.05 using a two‑tailed test, that is, testing whether ?≠10.

What does the Statistical Applet: Statistical Power indicate is the power of this test, the probability that you will be able to reject the null hypothesis if your assumptions are correct?

power:

Definition Definition Measure of central tendency that is the average of a given data set. The mean value is evaluated as the quotient of the sum of all observations by the sample size. The mean, in contrast to a median, is affected by extreme values. Very large or very small values can distract the mean from the center of the data. Arithmetic mean: The most common type of mean is the arithmetic mean. It is evaluated using the formula: μ = 1 N ∑ i = 1 N x i Other types of means are the geometric mean, logarithmic mean, and harmonic mean. Geometric mean: The nth root of the product of n observations from a data set is defined as the geometric mean of the set: G = x 1 x 2 ... x n n Logarithmic mean: The difference of the natural logarithms of the two numbers, divided by the difference between the numbers is the logarithmic mean of the two numbers. The logarithmic mean is used particularly in heat transfer and mass transfer. ln x 2 − ln x 1 x 2 − x 1 Harmonic mean: The inverse of the arithmetic mean of the inverses of all the numbers in a data set is the harmonic mean of the data. 1 1 x 1 + 1 x 2 + ...
