Analysis of 6.8 Ounce Bottling Process
The distribution is significantly normal, as the value of skewness falls within the range from -2* Std. Error of Skewness to 2* Std. Error of Skewness.
Median is the best measure of location as:
Not highly influenced by the frequency of occurrence of a single value
Not pulled by extreme values
200.2 is the value which occurs most frequently
About 95% of the data falls between (mu-2sigma to mu+2sigma)
Bottling process is working fine as minimal amount of bottles are filled with less than the normal quantity.
Analysis of Traditional 20 Ounces of Bottling Process
The distribution is significantly normal.
Mean, mode and median values are relatively close to classify the distribution as +vely or –vely skewed.
According to 95% confidence interval values lie btw 19.9985 to 20.0071.
Standard deviation is pretty small and helps us to come to a conclusion that most of the values are close to mean.
Almost all the bottles are filled uniformly and any chances of great variation in filling volumes is minimal.
