Jack found an average of 20 squirrels in the park that he could estimate the weight of all squirrels in the park. Is this an example of descriptive or inferential statistics? Is this a population or sample? The mean score on a Math Test is 82. The Math Scores of 15 randomly selected people are 98, 75, 62, 95, 85, 52, 77, 87, 92, 90, 80, 94, 68, 72, 99. Find u and x. A survey asked a sample of vacationers how far they drove to get to their destination. What is the margin of error if the interval estimate is (200 miles, 250 miles)? What is the length of the interval? If you know the point estimate and the margin of error, how do you determine the interval estimate? Point estimate: 110 Margin of error: 8 ]
