randomly selected cans of coke are measured for the amount of cola in ounces. The sample values obtained have a mean of 12.2 ounces. the standard deviation of the population is assumed to be 0.8 ounces. I calculate a confidence interval and determine the upper limit to be 12.5 and the lower limit to be 11.9. use the 68-95-99.7. Empirical rule of Thumb to answer the following questions. is my confidence level closer to 95% or 99%? if i redo my calculations using a sample of 100, will my confidence interval (for either 95% or 99%) be greater or less than for a sample of 64? greater 95%; less than 95%, greater 99%, less than 99%,
