To answer the problem above, we need first to know what median and mean means. In statistics median is the middle of the listed value data, while mean is the average of all the value of listed data. Both are kinds of averages so the mean is most like about 28 pounds.

Solution :

Median weight of a checked bag is= 27.5 pounds

it means , if there are n bags , the middlemost bag has weight 27. 5 pounds.

For , a data set, if it is symmetrical on both sides that is if difference between two succeeding values are same,then

Median = Mean

Otherwise , in some cases

Either, Median > Mean or Mean > Median.

Supposing each bag to be Equivalent, that is if they have equal weight,

Mean can't exceed ≥ 27.5 Pounds

Option B : The mean is most likely exactly 27.5 pounds,  is true about the given statement The median weight of a checked bag is 27.5 pounds.
