Use technology and a​ t-test to test the claim about the population mean μ at the given level of significance α using the given sample statistics. Assume the population is normally distributed.   ​Claim: μ>79​; α=0.10     Sample​ statistics: x=79.3​, s=3.3​, n=27   What is the​ P-value of the test​ statistic?   ​P-value=enter your response here ​(Round to three decimal places as​ needed.)

Choose the appropriate statistical test. When computing, be sure to round each answer as indicated. A dentist wonders if depression affects ratings of tooth pain. In the general population, using a scale of 1-10 with higher values indicating more pain, the average pain rating for patients with toothaches is 6.8. A sample of 30 patients that show high levels of depression have an average pain rating of 7.1 (variance 0.8). What should the dentist determine? 1. Calculate the estimated standard error. (round to 3 decimals). [st.error] 2. What is thet-obtained? (round to 3 decimals). 3. What is the t-cv? (exact value) 4. What is your conclusion? Only type "Reject" or Retain"

Please answer the questions in the photo. For Question 1, B has been selected BUT that could possibly not be the right answer. Please select the correct answer for Question 1 & 2.

Below is the finishes question to the last question of the problem.    Reject / fail to reject H0. At the 4​% significance​ level, there is / is not enough evidence to support / reject the claim

None
