Ответ:
The standard deviation would be 6.1947.
Step-by-step explanation:
Since we have given that
Mean = μ = 290
Weight of coffee beans = x = 283 grams
Since P(Z<z)=13% = 0.13
We need to find the standard deviation:
Using the standard normal table,
P(Z<-1.13)=0.13
So, we get that
z = -1.13
Using the z-score formula, we get that
Hence, the standard deviation would be 6.1947.
