The weights (to the nearest pound) of some boxes to be shipped are found to be: weight 65 68 69 70 71 72 90 95 frequency 1 2 5 8 7 3 2 2 explain why or why not this could be represented by a bell curve (a normal distribution).

Answer with explanation:

Weight       6568697071729095

frequency12587322

In a normal distribution the data  from the  left and right hand side of the median must have equal frequency.

Here Median lies between 70 and 71

( since median is the central tendency of the data)

Hence,

Median=(70+71)/2=70.5

The weights on the left and right hand side of the median do not have same frequencies.

Hence, this could not  be represented by a bell curve (a normal distribution)
