In a test of a gender-selection technique, results consisted of 282 baby girls and 300 baby boys. Based on this result, what is the probability of a girl born to a couple using this technique? Does it appear that the technique is effective in increasing the likelihood that a baby will be a girl? The probability that a girl will be born using this technique is approximately nothing. (Type an integer or decimal rounded to three decimal places as needed.)
Solutions
Expert Solution
Solution :
The total sample of the study was,
282 + 300 = 582, then
P(girl) = 282 / 582 = 0.485
The probability that a girl will be born using this technique is approximately = 0.48
Yes because the technique is effective if the probability of having a girl baby is significantly
less than the expected probability of having a girl baby, 0.5
