A large cooperation has quality control over its fertilizers. The fertilizes are composed of nitrogen. The fertilizer requires 3

JulsSmile [24]

Answer:

It is impossible that the mean of the sample of 100 fertilizers less than 2 mg.

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 2.5 mg

Standard Deviation, σ = 0.1 mg

We are given that the distribution of percentage of nitrogen score is unknown.

Formula with sampling:

$z_{score} = \displaystyle\frac{x-\mu}{\frac{\sigma}{\sqrt{n}}}$

P( mean of the sample of 100 fertilizers less than 2 mg)

P(x < 2)

$P( x < 2) = P( z < \displaystyle\frac{2-2.5}{\frac{0.1}{\sqrt{100}}}) = P(z < -50)$

Calculation the value from standard normal z table, we have,

$P(x < 2) =0 = 0\%$

Thus, it is impossible that the mean of the sample of 100 fertilizers less than 2 mg.
