Question

Select Yes or No to state whether each data set is likely to be normally distributed.

the weights of the babies born at a hospital Yes/No

the number of babies born each month at a hospital Yes/No

the number of rooms on each floor of a hospital Yes/No

the lengths of the babies born at a hospital Yes/No

Answer 1

1) Yes, 2) Yes, 3) No, 4) Yes

Answer 2

Explanation:

Given are data sets and we have to find which are normally distributed

i) the weights of the babies born at a hospital

-- Yes. Because majority or peak will have mean = median =mode weight with less and less number deviating from the mean more than 3 std deviations.

ii) the number of babies born each month at a hospital

--no. This need not be normal, also this is a discrete variable

iii) the number of rooms on each floor of a hospital

-- No this is finite in number and discrete

iv) the lengths of the babies born at a hospital Yes

Because majority or peak will have mean = median =mode weight with less and less number deviating from the mean more than 3 std deviations.
