Answer:
Step-by-step 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.
