A researcher computes a 90% confidence interval for the mean weight (in ounces) of widgets produced in a computer factory. The interval is (7.2, 8.9). Which of these is a correct interpretation of this interval? (A) There's a 90% chance the population value is between 7.2 and 8.9 oz. (B) Ninety percent of all sample means are equivalent to the true mean weight of all the widgets. (C) If you drew many samples of size n and constructed a confidence interval from each sample, 90% of the intervals would contain the true population value. (D) Out of all the widgets produced in the factory, 90% weigh between 7.2 and 8.9 oz
