Question

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 1

Because the data is not a normal distribution because the second half of the data is too far away from the first half i think its also called unproportional or something like that feel free to add me as a friend

Answer 2

Answer with explanation:

Weight       65 68 69 70 71 72 90 95

frequency 1 2 5 8 7 3 2 2

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)
