Please use the following information to answer questions 4c-4e: To evaluate the effect of a treatment, a sample of n = 8 is obtained from a population with a mean of µ = 40, and the treatment is administered to the individuals in the sample. After treatment, the sample mean is found to be x̅ = 35.   If the sample variance is s2 = 32, are the data sufficient to conclude that the treatment has a significant effect? Use a two-tailed test with α = .05.    4c. Compute the test statistic (t-observed) for the mentioned sample (MUST SHOW WORK FOR THIS PROBLEM).     4d. Based on the calculated test statistic, would you reject the null hypothesis established in question 4a (MUST SHOW WORK FOR THIS PROBLEM)?   Group of answer choices: a. yes b. no     4e. Based on the previously conducted steps, can it be concluded that the treatment had a significant effect (MUST SHOW WORK FOR THIS PROBLEM)?   Group of answer choices: a. yes b. no
