Answer:
For a level of 0.0174 or more of nitrogen oxide, the probability of fleet is 0.01.              
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 0.02 g/mi
Standard Deviation, σ = 0.01 g/mi
Sample size, n = 81
We are given that the distribution of  level of nitrogen oxides is a bell shaped distribution that is a normal distribution.
Standard error due to sampling:

Formula:
 
We have to find the value of x such that the probability is 0.01
P(X > x)  
 
  
 
  
 
  
Calculation the value from standard normal z table, we have,  
 
 
For a level of 0.0174 or more of nitrogen oxide, the probability of fleet is 0.01.
