Answer:
The total of water bottles becomes dependent of the hours taken and how data changes this can establish a true time frequency through multiplying together last stage. These 3 totals can also be multiplied if being asked for the mean. However is they are lined up in 2 data lists then added totals on each list are made as step one and multiplication of the individual untotaled totals can show a 3rd total. The mean of such data to understand loss of time in any sequence of repeat changed data the multiple of 3 totals above of one set data= Totals = independent w x independant h = mean dependent (f) where totals for bottles per hour can be arranged in groups and totaled separately as both stay independant. so that = tw x th x f becomes the mean.
Step-by-step explanation:
It can only become an independent mean and value when 2 multiple totals are sought before any mean is required, as hours increase this is one total, amount of bottles filled is two values.- matched up in such list can show bottles and hours taken, but showing average for example would require discreet mean calculations. Mean test and (frequency) expands such understanding.
