Suppose that the distance of fly balls hit to the outfield (in baseball) is normally distributed with a mean of 256 feet and a standard deviation of 60 feet. We randomly sample 49 fly balls. Part (a) If X = average distance in feet for 49 fly balls, then give the distribution of X. Round your standard deviation to two decimal places. X ~ , . Part (b) What is the probability that the 49 balls traveled an average of...

In 2018 the average distance of a fly ball is 320 feet with a standard deviation of 25 feet. Suppose we randomly sample 100 fly balls, use the central limit theorem to answer the following questions. 1 State the mean and standard deviation for average distance of the 100 fly balls using the central limit theorem. 2. Find the probability that the 100 balls traveled an average of less than 315 feet? 3. Still using the central limit theorem but...

Your friend tells you that the proportion of active Major League Baseball players who have a batting average greater than .300 is less than 0.7, a claim you would like to test. The hypotheses here are Null Hypothesis: p ≥ 0.7, Alternative Hypothesis: p < 0.7. If you take a random sample of players and calculate p-value for your hypothesis test of 0.3030, what is the appropriate conclusion? Conclude at the 5% level of significance. Question 15 options: 1) The...
