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!!!

Solve the given proportion for x.  Answer to two decimal places. x/5=16/21​
Angelina_Jolie [31]

\\ \sf\longmapsto \dfrac{x}{5}=\dfrac{16}{21}

\\ \sf\longmapsto 21x=16(5)

\\ \sf\longmapsto 21x=80

\\ \sf\longmapsto x=\dfrac{80}{21}

\\ \sf\longmapsto x=3.6
