Problem 3 Part A: An experimental diet to induce weight loss was followed for one week by a randomly selected group of 5 students with the following results. Student Loss in Pounds 2. 1 2. 7 0.8 2.2 1.2 U'l-h-UJMII Find a point estimate for the average weight loss in pounds after one week on this diet. Is this an unbiased estimate of the population mean? Explain. Part B: A consumer testing organization reports that at 99% confidence that the true average content of the drinks is between 10.8 to 11.4 ounces. The sample revealed an average content is 11.1 ounces. Assuming the standard deviation of the population is 1.23, determine the size of the sample. Part C: In a sample of 2000 systems sold, 30 systems were defective. Determine a 90% confidence interval for the percentage of defective systems
