Answer: the value of the test statistic is 2.11

Step-by-step explanation:

Given that;

sample mean x" = 95

standard deviation σ = 3

sample size n = 40

Null hypothesis H₀ : μ = 94

Alternative hypothesis H₁ : μ ≠ 94

Level of significance ∝ = 0.02

Test statistic value

z = (x" - μ) / ( σ/√n)

we substitute

z = (95 - 94) / ( 3/√40)

z = 1 / 0.4743

z = 2.11

Therefore, the value of the test statistic is 2.11
