Question

The first step in testing a hypothesis is to establish _______.

a not rejectance hypothesis and a rejection hypothesis
a power function
a null hypothesis and alternative hypothesis
an indirect hypothesis

Which of the following is not one of the steps for hypothesis testing?
Choosing a cutoff value from your population to determine how close your sample is to the population value.
Calculating the test statistic with the summary sample statistics.
Drawing a conclusion based on the results of your test.
Deciding whether to reject or fail to reject the null hypothesis.

The null and alternative hypotheses divide all possibilities into:
two sets that overlap
two non-overlapping sets
two sets that may or may not overlap
as many sets as necessary to cover all possibilities

The alternative hypothesis states that there is no difference/no effect.
True
False
One-tailed alternatives are phrased in terms of:
¹
< or >
» or =

There is one critical value and the area to the left of it is 0.90.

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 + ...
