Solution

The correct option is A 4 kg
$M e a n = \frac{S u m o f a l l w e i g h t s}{N u m b e r o f b a b i e s}$

Sum of all weights = 3.7 + 4.1 + 3.9 + 4.3 + 4.5 + 3.5 + 4
= 28

Number of babies = 7

$M e a n = \frac{28}{7}$
= 4

The weights of 7 new born babies in a hospital on a particular day (in Kg.) is 3.7, 4.1, 3.9, 4.3, 4.5, 3.5, 4.0

Find the mean weight

The correct option is A 4 kg
$M e a n = \frac{S u m o f a l l w e i g h t s}{N u m b e r o f b a b i e s}$

Sum of all weights = 3.7 + 4.1 + 3.9 + 4.3 + 4.5 + 3.5 + 4
= 28

Number of babies = 7

$M e a n = \frac{28}{7}$
= 4
