For a large n, it says the population is approximately normal. d. For a large n, it says the sampling distribution of the sample mean is approximately normal, regardless of the shape of the population. The correct answer is: For a large n, it says the sampling distribution of the sample mean is approximately normal, regardless of the shape of the population. Which of the following is/are true? Select one: a. If the p-value is not less than Alph, then the null hypothesis is plausible. b. As long as the p-value is less than Alph, we can conclude there is statistical significance. c.
