Answer

Explanation:

Step1: Calculate total number of babies

$277 + 11=288$

Step2: Calculate probability of female birth

$\text{Probability}=\frac{\text{Number of female babies}}{\text{Total number of babies}}=\frac{277}{288}\approx 0.962$ Since the probability of having a female baby with this technique is approximately $0.962$, which is much higher than the natural - expected probability of around $0.5$ for a female birth.

Answer:

The probability that a female will be born using this technique is approximately $0.962$. Yes
