coca-cola is wary that their machines are getting too old and that they are not consistent. they randoly select 15 bottles of coca-cola and got a mean of 16.95 ounce sith a standard deviation of .67 ounce. assume the population is normally distributed. A- construct a 95% confidence interval for the population standard deviation B if the standard deviation is 1-ounce or more, coca-cola need to replace all of their machines. looking at part a) confidence interval should they considered rplacing all of their machines? Explain why or why not
