Basic Math

We work for Cola Company and there have been some discussions onwhich pressure setting is best for filling out bottles. If weoverfill the bottles then we are spending money we do not need to.If we are under filling the bottles we run the risk ofdissatisfaction of the customers. If we can fill the bottles usinga higher psi we can run the line faster and thus increase ourproduction. Our current fill pressure is 25psi. Management wants toknow if there is a different variation from the standard betweenthe two pressure settings.

ml (25psi volume): 1007.2, 1008.4, 1010.2, 1011.2, 1008.0,1009.0, 1011.4, 1013.4, 1010.6, 1010.9

ml (30psi volume): 1001.2, 1003.1, 1003.6, 1001.4, 1002.7,1004.3, 1002.6, 1005.0, 1003.7, 1004.4

Sample size of first set =

Sample size of second set =

Sample mean of first set =

Sample mean of second set =

Sample standard deviation of the first set =

Sample standard deviation of the second set =

Estimate of variance =

Confidence Coefficient =

Alpha =

Calculated Degrees of Freedom =

Calculated Test Statistic =

What can you conclude by observing your confidence limits? (Nodifference or there is a difference?) =
