A soft drink bottling machine fills bottles with fluid volumes that are normally distrbuted with a mean of 250 ml and a standard deviation of 0.4 ml.
A- find probabilty that any one bottle is filled with more than 251ml
B- calculate the value of C for which 95% of the bottles contain a volume in ml between (251-c) and (251+c)
C- if the bottles are packed at random in six packes find the probabilty that any set of six bottles contains less than a total volume of fluids less than 1503 ml.
