What are the five steps in the hypothesis testing procedure
What are the five steps in the hypothesis testing procedure? Are the steps followed in sequence? Explain why or why not. How does the five-step procedure for hypothesis testing differ when comparing two groups using a t- or z-test? How is the process similar?
Solution
There are five steps in hypothesis testing:
In hypothesis testing we make assumptions about the level of measurement of the variable, the sampling method, the shape of the population distribution, and the sample size. In our example, we made these assumptions:
The five steps of the hypothesis testing should be followed in order, because each step is reliant of the step before it. The T-test is a statistical examination of two population means. A two-sample t-test examines whether two samples are different and is commonly used when the variances of two normal distributions are unknown and when an experiment uses a small sample size
How does the five-step procedure for hypothesis testing differ when comparing two groups using a t- or z-test?
they differ when we know the sample variance of population or we dont know, also for the sample size
How is the process similar?
it is the same formula , only change what table you will be use
