Which of the following statements is true? (a) If the calculated value of F statistic is higher than the critical value, we reject the alternative hypothesis in favor of the null hypothesis. (b) The F statistic is always nonnegative as SSR, is never smaller than SSRur. (C) Degrees of freedom of a restricted model is always less than the de- grees of freedom of an unre- stricted model. (d) The F statistic is more flexible than the t statistic to...

P-value is the probability, computed assuming H0 is true, that the test statistic would take a value as extreme or more extreme than that actually observed. Given the sample at hand, it is the smallest level of significance at which H0 would be rejected. It depends on the sample (hypotheses as well) and is hence also a test statistic. Generate 50 samples of size n=10 from a normal distribution with mean μ=1 and variance σ2=4. For each sample, use the...

p-value Approach: The p-value is the smallest significance level at which the null hypothesis is rejected. While using the normal distribution, suppose, z = Zobserved is the test statistic value for testing the hypothesis about a population mean. This test statistic value is usually negative for a left-tailed test and is usually positive for a right-tailed test. The p-value is obtained with the help of the Standard Normal Distribution Table (Table IV). 1. For a left-tailed test, p-value = P(z<...

Which of the following is about F-test is NOT true? Group of answer choices a. F-test is used to test whether two independent populations have the same mean. b. F-test is used to study the variances of two populations in order to test the assumption of equal variances c. The test statistic for F-test follows F distribution d. The lower-tail critical value of the F distribution FL is computed by taking the reciprocal of FU.
