A sample of n=25 individuals is randomly selected from a population with a mean of p=65, and a treatment is administered to the individuals in the sample. After treatment, the sample mean is found to be 70. If the sample standard deviation is s=20, the data is sufficient enough to conclude that the treatment has a significant effect using a two-tailed test with alpha level of 0.05, or that you conclude that you reject your null hypothesis. You have to do the 4-step hypothesis testing procedure to determine the answer to this item. Select one: O True O False

Question
A sample of n=25 individuals is randomly selected from a population with a mean of p=65,
and a treatment is administered to the individuals in the sample. After treatment, the
sample mean is found to be 70. If the sample standard deviation is s=20, the data is
sufficient enough to conclude that the treatment has a significant effect using a two-tailed
test with alpha level of 0.05, or that you conclude that you reject your null hypothesis. You
have to do the 4-step hypothesis testing procedure to determine the answer to this item.
