Question 8 (2 points) Suppose instead that a population is known to have a mean of 10.4 and a standard deviation of 0.3. What is the probability that a random sample will have a mean of 9 or less? Express your answer with four decimal points. A/ Question 9 (2 points) Suppose that we are performing a one-tailed test and are trying to find the t-statistic associated with a probability of 0.05. If the sample size is 3, what is the associated t- statistic? Use the provided t table in the Module to aid you in answering the question. A/
