For this question, you'll be using the Normal Distribution in Statkey. In Statkey, go to "Normal" in the Theoretical Distributions. Situation: A sample of baseball games shows that the mean length of those games is 179.83 minutes. The standard error for this mean is 3.75. Does this provide evidence to suggest average length of a baseball game is more than 170 minutes? Q1: What is the relevant sample statistic? What is the correct notation for this value? Select an answer = Q2: What population parameter are we looking at? What is the correct notation for this value? Select an answer Q3: What are the null and alternative hypotheses you'd use to explore this question? Ho: ? Ha ? Q4: What is the standardized test statistic, z Statistic SE Ho . Round to three decimal places. == Q5: Use the standard normal distribution to find your p-value. p-value = Q6: Use your p-value to make your formal conclusion to this test at the a = 0.05 level. Select an answer Q7: State the conclusion to this test in context. For this question, you'll be using the Normal Distribution in Statkey. In Statkey, go to "Normal" in the Theoretical Distributions.
