The mean and standard deviation for the number of boys in the 950 babies are 475 and 15.41, respectively
<h3>How to determine the mean and the standard deviation?</h3>From the complete question, we have:
P(boy)= 0.5
Sample size = 950
The mean is then calculated as:
This gives
Evaluate
The standard deviation is calculated as:
This gives
Evaluate
Hence, the mean and standard deviation for the number of boys in the 950 babies are 475 and 15.41, respectively
