Answer:
t = 34.548
Step-by-step explanation:
Here X₁ = Solid values / n
= 26.3 +25.3+26.1+25.6+26.7+25.9/6
=155.9 / 6
=25.984
X₂ = Liquid values/n
= 16.9 +16.6+16.5+17.4+17.4+17.2 / 6
=102/6 = 17
Formula for the sample standard deviation is
we get
s₁ = 0.49967
s₂ = 0.3949
Construction of hypothesis
H₀ :μ₁ = μ₂
H₁ : μ₁ ≠ μ₂
Apply test statistic formula we get the value
putting all these values
t = 25.984 - 17 / √ (o.49967)²/6 + (0.39497)²/6
t = 34.548
