An engineer has designed a valve that will regulate water pressure on an automobile engine. The valve was tested on 160 engines

abruzzese [7]

Answer:

Test statistic Z = 2.1097

Step-by-step explanation:

Step(i):-

Given that size of the sample 'n' = 160

Given that mean of the Population(μ) = 5.3pounds/square inch

The Standard deviation of the population(σ) = 0.6

Mean of the sample(x⁻) = 5.4

Level of significance =0.1

Step(ii):-

Test statistic

$Z = \frac{x^{-}-mean }{\frac{S.D}{\sqrt{n} } }$

$Z = \frac{5.4-5.3}{\frac{0.6}{\sqrt{160} } }$

Z = 2.1097

Final answer:-

Test statistic Z = 2.1097
