A sample of n = 25 individuals is randomly selected from a population with a mean of 65 and a treatment is administered to the individuals in the sample. After treatment, the sample mean is found to be M = 70 and the standard deviation is s = 10. What is the Critical Value? Assume a two-tailed test with alpha = .05

A random sample of n = 25 individuals is selected from a population with µ = 20, and a treatment is administered to each individual in the sample. After treatment, the sample mean is found to be M = 22.2 with SS = 384. What was the critical value? What is the test statistic? Did you retain or reject the null? Compute and interpret Cohen's d. Compute the 95% confidence interval.

A random sample of n = 25 scores is selected from a normal population with a mean of µ = 40 and σ = 10. After a treatment is administered to the individuals in the sample, the sample mean is found to be M = 44. Sketch the distribution and label the critical region. Use all 5 steps of the hypothesis test (α = .01) to determine if the treatment significantly increased scores.

Conduct the appropriate test. A simple random sample of size $n=15$ is drawn from a population that is normally distributed. The sample mean is found to be $23.8,$ and the sample standard deviation is found to be $6.3 .$ Test whether the population mean is different from 25 at the $\alpha=0.01$ level of significance.
