PSY 230 Week 5 Review

The alpha, α, is what?

To conclude a hypothesis test we compare the z-value to the alpha value

When running a hypothesis test we are testing the alternate hypothesis.

The following is an appropriate conclusion for a hypothesis test: Fail to reject the H_a

If the p-value is less than alpha, we reject the null hypothesis

You run a hypothesis test with an α= 0.01 and find you p-value to be 0.007. You will "Fail to reject H₀"

δ is the sample standard deviation

To conclude a hypothesis test we compare the beta value to the z-value

μ is the sample mean of a data set

If we know the population std dev and have a sample size larger than 30, which test statistic is appropriate to use?

The first step in completing a hypothesis test is a hypothesis statement

Find the p-value for a left tail test when z = - 1.61

To conclude a hypothesis test we compare what two values?
