QUESTION 2 10 points Save Answe When calculating confidence intervals E is the margin of error. This represents the distance from middle of the confidence interval to either endpoint. For proportions this is expressed as: p + F and for means it is expressed as: x+ E Write your confidence interval in inequality symbols and interval notation. Use p for proportions and mu for means. Please do not put spaces between symbols and numbers to help with grading. 1. A sample of 200 computer chips is obtained and 4% are found to be defective. If the margin of error is 0.0357, construct the confidence interval for the percentage of all computer chips that are defective. Inequality: Interval: 2. Suppose a sample of 19 high school baseball pitchers is taken. They have an average pitching speed of 80 miles per hour. If the margin of error is 5.2, construct the confidence interval for the average pitching speed of all high school baseball pitchers. Inequality: Interval: 3. A sample of 4 plane crashes finds that the average number of deaths was 49. If the margin of error is 43.8068, construct the confidence interval for the average number of deaths per plane crash. Inequality: Interval: 4. A new restaurant is opening, and the manager wants to know what percentage of orders is completed correctly by the staff. In a random sample of 100 orders, he finds that 93 are correct. The margin of error is 0.042 for a 90% confidence interval. Construct the confidence interval for the true percentage of all correct orders at the restaurant. Inequality: Interval
