Using a t-distribution with 37 degrees of freedom, find the rejection region for a lower-tailed hypothesis test about a population mean at the 0.05 significance level.
You are conducting a two-tailed hypothesis test to see if your sample mean (x̄) differs significantly from your population mean (μ = 50). Your alpha level is 0.05 (α = 0.05). Sample data: 53, 56, 59, 64, 55, 42, 36, 58, 39, 53, 62, 60, 64, 53, 42, 53, 65, 60, 61, 63 You will need to: h) State your alternative hypothesis and null hypothesis i) Calculate the sample mean (x̄) j) Calculate the sample standard deviation (s) k) Calculate...
What is the critical value of a right-tailed Independent t-Test when you have 32 degrees of freedom, and alpha = 0.05? (Answer to 3 digits after the decimal point.)
For a two tailed t-test with 20 degrees of freedom using α = 0.05, the rejection region is defined as t values below or equal to _________or t-values above or equal to ______
State the total degrees of freedom for the following t-tests. (If you need to use ∞, enter INFINITY.) 1. n = 17 for a one-independent sample t-test 2. df1 = 14, n2 = 18 for a two-independent sample t-test 3. critical value = 1.645 for a one-tailed test, α = 0.05 4. critical value = 63.657 for a two-tailed test, α = 0.01

When performing a hypothesis test for the ratio of two population variances, the upper critical F value is denoted FR. The lower critical F value, FL, can be found as follows: interchange the degrees of freedom, and then take the reciprocal of the resulting F value found in table A-5. FR can be denoted Fα/2 and FL can be denoted F1-α/2 . Find the critical values FL and FR for a two-tailed hypothesis test based on the following values: n1...

The Student's t distribution table gives critical values for the Student's t distribution. Use an appropriate d.f. as the row header. For a right-tailed test, the column header is the value of α found in the one-tail area row. For a left-tailed test, the column header is the value of α found in the one-tail area row, but you must change the sign of the critical value t to −t. For a two-tailed test, the column header is the value...
