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
Answer:
52
