Answer: 0.129
Step-by-step explanation:
Let
denotes a random variable that represents the mean weight of babies born.
Population mean : 
Standard deviation: 
Sample size = 83
Now, the probability that the mean weight of the sample babies would differ from the population mean by greater than 54 grams will be :

hence, the required probability = 0.129
