- A chi-square independence test is to be conducted to decide whether an association exists between two variables of a populations. One variable has 4 possible values and the other variable has 2. What are the degrees of freedom for the χ2-statistic? answer:How do i find the p-value without using excel for a two tailed test? Z-score known.Explicate a null and alternative hypothesis in words and symbol and tell whether the test is directional or non directional. A random sample of 200 engineering students got a mean score of 62 in knowledge test in physics. In standardization of the test , μ=50
- Explain F test in ANOVA is the equivalent of a non-directional test.Hypothesis testing allows us to use an analytical process to determine if a hypothesis is retained OR rejected. This process compares a null hypothesis (HO), which states things as we believe they are, to an alternative hypothesis (HA), which proposes a change to what we believe exists. Respond to the following in a minimum of 175 words: Discuss the concepts of hypothesis testing, including what you are evaluating, when it should be used, and the differences between a one- and a two-tailed test. Describe an example from your own personal or professional experiences where you could apply a hypothesis test, and discuss how knowing that information helped you.Explain about lower tail test.
