Answer:
The test statistic | t | =4.45
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given that the first sample size n₁ = 36
Given that the second sample size n₂ = 34
Mean of the first sample x₁⁻ = 68.5
Mean of the second sample x₂⁻ = 70
<u><em>Step(ii):-</em></u>
Test statistic

Answer:
7
Step-by-step explanation:
Listing the factors of each number is one way, that is
factors of 35 : 1, 5, 7, 35
factors of 42 : 1, 2, 3, 6, 7, 14, 21, 42
The common factors are 1 and 7
The GCF is therefore 7
