Suppose you feel that the average stress level is, on average, greater than 200. The population standard deviation is 27. You test this claim by taking a random sample of 81 adults. The sample has a mean of 208.25.
What is the standard error of the sampling distribution?
What is the standardized sample mean?
Assuming the null is true, what is the probability of getting a sample mean as extreme as we did?
What can you conclude?
What is the 95% confidence interval of the sample mean?
