Answer:
The weight corresponding to which weight will be larger than 14% of times equals 427.635 grams.
Step-by-step explanation:
We need to find the value of weight that corresponds to 14% of area under the normal distribution curve
It is given that

Using standard normal distribution tables we find value of Z corresponding to 14% of the area as -1.080
Thus using the standard equation
