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:
P( mean of the sample of 100 fertilizers less than 2 mg)
P(x < 2)
Calculation the value from standard normal z table, we have,
Thus, it is impossible that the mean of the sample of 100 fertilizers less than 2 mg.
