2.7
g. What does it mean to be "95% confident" in this problem? Use the definition of confidence level.
a. 95% of all simple random samples of size 12 from this population will result in confidence intervals that contain the population mean
b. The confidence interval contains 95% of all samples
c. There is a 95% chance that the confidence interval contains the population mean
