Answer:

The value of test statistic

|Z| = |-2.2883| = 2.2883

Step-by-step explanation:

Step(i):-

Given that the mean of the Population = 57.7miles/gallon

The standard deviation of the Population = 1.9

The mean of sample x⁻ = 57.4

Given that the sample size 'n' =210

level of significance = 0.1

Step(ii):-

Test statistic

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

$Z = \frac{57.4-57.7}{\frac{1.9}{\sqrt{210} } }$

Z = -2.2883

|Z| = |-2.2883| = 2.2883

Final answer:-

The value of test statistic

|Z| = 2.2883
