Following are the weights (in kg) of 10 new born babies in a hospital on a particular day:
3.4, 3.6, 4.2, 4.5, 3.9, 4.1, 3.8, 4.5, 4.4, 3.6. Find the mean x.
उत्तर
The weight (in kg) of 10 new born babies
= 3.4, 3.6, 4.2, 4.5, 3.9, 4.1, 3.8,4.5,4 .4, 3.6
Mean (x) = `"Sum of weights"/"Total babies"`
`(3.4 + 3.6 + 4.2 + 4.5 + 3.9 + 4.1+ 3.8 + 4.5 + 4.4 + 3.6) / 10`

A football player scored the following number of goals in the 10 matches:
1, 3, 2, 5, 8, 6, 1, 4, 7, 9
Since the number of matches is 10 (an even number), therefore, the median
= `(5^("th") "observation" + 6^("th") "observation")/2`
= `(8 + 6)/2` = 7
Is it the correct answer and why?
