Answer: 0.129

Step-by-step explanation:

Let \overline{X} denotes a random variable that represents the mean weight of babies born.

Population mean : \mu= \text{3316 grams,}

Standard deviation: \text{324 grams}

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 :

P(|\mu-\overline{X}|>54)=1-P(\dfrac{-54}{\dfrac{324}{\sqrt{83}}}

hence, the required probability =  0.129
