6. Suppose we collected a sample of size n = 100 from some population and used the data to calculate a 95% confidence interval for the population mean. Now suppose we are going to increase the sample size to n = 300. Keeping all else constant, which of the following would we expect to occur as a result of increasing the sample size? 1. The standard error would decrease. 2. Width of the 95% confidence interval would increase. 3. The margin of error would decrease. II and III I and III I and II I, II, and III None 1 point
