Validity is more critical to measurement than reliability. A valid measurement is reliable, but a reliable measurement may not be valid. Do you agree with these statements? Explain your answer. Provide examples to support your rationale.
Test the hypothesis that there is no difference between the means of retailers (α= .05). Select a multiple comparison test, if necessary, to determine which groups differ in mean sales (α= .05).
Determine the test value? Use α = 0.05. (Use the variances unequal formula).

A random sample of 100 computers showed a mean of 115 gigabytes used with a standard deviation of 20 gigabytes. What is the standard error of the mean?
Suppose that a population is normally distributed with a mean of 100 and a standard deviation of 15. Would it be unusual for the mean of a sample of 3 to be 115 or more?
They hope to use a sample size such that, with probability 0.95, the error will not exceed 0.04. What sample size will ensure this, regardless of what sample proportion value occurs when they gather the sample?
Is it true that one of the important properties of time series models is that some sort of pattern in the data over time should be detected first and then used within the model?
For a normal population with u. = 80 and a = 20 which of the following samples is least likely to be obtained?
