Answer:
The answer is : 0.0597
Step-by-step explanation:
Population mean = μ = 80
Standard deviation = σ = 20
Sample = N = 60
σ_mean = σ/√N
= (20)/√(60) = 2.582
Now we will find z1 and z2.
z1 = {(84) - μ}/σ_mean =
z2 = {(88) - μ}/σ_mean =
Now probability that the sample mean will be between 84 and 88 is given by:
Prob{ (1.549) ≤ Z≤ (3.098) } = (0.9990) -(0.9393) = 0.0597
Answer:
Julie buy pounds of turnips.
Step-by-step explanation:
We are given that Julie bought a bag of parsnips that weighed () pounds. She also bought a bag of turnips that weighed (
) times as much as the parsnips.
We have to find how many pounds of turnips did Julie buy.
Firstly, the weight of a bag of parsnips that Julie bought = =
pounds
Now, it is stated that she bought a bag of turnips that weighed () times as much as the parsnips, that means;
Weight turnips bag =
=
=
So, Julie buy pounds of turnips.
