A grocery store separates its shrimp into 3 categories: baby, medium, and jumbo. Use the information provided below to determine the weights of the shrimp receiving each size designation.
Shrimp weights are normally distributed with:
mean=18.8 grams
standard deviation= 5.3 grams
The smallest 20% of shrimp will be designated as baby. The largest 25% of shrimp will be designated as jumbo. Everything else will be designated as medium.
Shrimp weighing less than _ grams will be designated as baby.
Shrimp weighing more than _ grams will be designated as jumbo.
mean=18.8 grams
standard deviation= 5.3 grams
The smallest 20% of shrimp will be designated as a baby. The largest 25% of shrimp will be designated as jumbo. Everything else will be designated as a medium.
Shrimp weighing less than ____grams will be designated as the baby?
P(z<z1)=0.2
Using standard normal table we get
Shrimp weighing less than 14.34 grams will be designated as the baby.
B)
Shrimp weighing more than _ grams will be designated as jumbo.
P(z>z1)=0.25
Using standard normal table we get
Shrimp weighing more than 22.375 grams will be designated as jumbo.
