(15.34) The level of nitrogen oxides (NOX) in the exhaust of cars of a particular model varies Normally with mean 0.21 g/mi and
MrMuchimi

Answer:

a level of significance of 0.01 = 1%

Step-by-step explanation:

given

Z = 0.0001

mean μ=0.21 g/mi

variate x= 0.21 + 0.03

standard deviation σ= 0.05 g/mi.

N = sample population  20 cars

z = (x −μ )/[σ /√N  ]

Z =\frac{x −μ}{\frac{σ}{√N} }

Z = 0.03/ (0.05/√20) = 0.03/0.0111

Z = 2.63 +- 0.0001

Z=  2.6301  or 2.6299

checking the level of significance table from a statistical book gives

a level of significance of 0.01 = 1%

therefore the null hypothesis is accepted.
