m. Assume that the zinc mass for the population of AAA batteries is normally distributed. A researcher has constructed a 90% confidence interval about the population mean zinc mass in grams using a random sample of 100 AAA batteries. The resulting confidence interval is between 2.05 grams and 2.09 grams. Which of the following statements is TRUE? (1) There is a 90% probability that the true population mean zinc mass for AAA batteries is between 2.05 grams and 2.09 grams. (2) 90% of the population of AAA batteries has the average between 2.05 grams and 2.09 grams. (3) Based on the resulting confidence interval, the population mean is 2.07 grams. (4) Based on the resulting confidence interval, the margin of error is 0.02 grams. (5) All of the above
