If we run a one-sample t-test and get a t-stat=6.74, with n=7, the p-value under one-sided conditions is:
This is one sided test and it is right tailed test
The calculated value of test statisitc is 6.74
degrees of freedom = 7 - 1 = 6
p-value = P(t > 6.74) = 0.0003

The one-sample t statistic from a sample of n = 21 observations for the two-sided test of H0: μ = 60, Ha: μ ≠ 60 has the value t = –1.98. Based on this information: we would reject the null hypothesis at α = 0.05. All of the answers are correct. 0.025 < P-value < 0.05. we would reject the null hypothesis at α = 0.10

11. if a p-valenfor a 2-sided test equals .065, the p-value for the 1-sided test using the same sample data will not be signifciant at the 1% level true of false 7. when a smaple stastic is close to the hypothesize the population parameter, the p-value for a significance test will typically be low. true or false
We are looking to calculate the power of a one-sided test from n independent observations xi from a N (µ, σ2 ) distribution with a null hypothesis of H0 : µ = µ0 and an alternative H1 : µ > µ0. Supposing that we know σ2, we can form a test statistic T = (x¯ − µ0)/(σ/√n) and reject the null hypothesis when T > 1.645. This test has level α = 0.05. We want a formula for the power...
What is the critical z value for a one sided test when α = .01 and n = 25? What is the critical z value for a two sided test when α = .01 and n = 25? What is the critical t value for a one sided test when α = .01 and n = 25? What is the critical t value for a two sided test when α = .01 and n = 25?

c. Run a two-sample paired t-test for means to test your hypothesis, using a confidence level of 95%. To show whether it is a one-tail test or a two-tail test, highlight the significant values in the Excel output, including your p-value, critical t, and t stat. and write a sentence or two to interpret the results. should the null hypothesis be rejected? In EXCEL PLEASE TABLE C9-2: Wife and Husband Feedback Scores on 1-7 Scale + Same Day or Not...
Run a one sample t-test for HGHTI_P to test if the CHIS sample is significantly different from 68(the average height in the U.S.). What can you conclude based on the results of your test (Hint: what does the p-value tell you?)? Do you reject the null hypothesis, or fail to reject the null hypothesis? Does the CHIS sample population have a statistically significant different average height than 68 inches tall?
Can you help with the P-VALUE, and
