Answer:

Test statistic Z = 2.1097

Step-by-step explanation:

<u><em>Step(i):-</em></u>

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

<u><em>Step(ii):-</em></u>

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

<u><em>Final answer</em></u>:-

Test statistic Z = 2.1097
