Expression simplified: 
Step-by-step explanation:
The expression that we have in this problem is:

The first type of operation that we have to solve in such expression are multiplication/division.
In this expression, there is only one multiplication, that is:

So we can rewrite the expression as

Now we can evaluate the sum of the similar terms: in this case, similar terms are only 3 and 4, and their sum is

Therefore, the expression can be rewritten as

Answer:
The test statistic = -0.93
Step-by-step explanation:
The test statistic is given by the formula
z = (X₁ - X₂) ÷ √(σₓ₁² + σₓ₂²)
where X₁ = proportion of data of South Korean tourists = (57/134) = 0.425
X₂ = proportion of other country tourists = (72/150) = 0.48
σₓ₁ = standard error in data 1 = √[p(1-p)/n]
= √(0.425 × 0.575/134) = 0.0427
σₓ₂ = standard error in data 2 = √[p(1-p)/n]
= √(0.48 × 0.52/150) = 0.0408
z = (X₁ - X₂) ÷ √(σₓ₁² + σₓ₂²)
z = (0.425 - 0.48) ÷ √(0.0427² + 0.0408²)
z = -0.055 ÷ 0.0590586996
z = -0.9313
Hope this Helps!!!
