Answer:

(a) 151 (b) 21430 (c) p value = 0.008 (d) We reject the null hypothesis and conclude that there is a significant difference between average expenditure of all tourist who visited the cities

Explanation:

Given that:

Let the random sample n₁ = 89

The average (x₁) = $2860

The standard deviation(σ) = $126

Random sample n = 64

The average (x₂) =  $2935

The standard deviation(σ) = $138

Now,

(a) = The test degree of freedom =  n₁ +n₂₂ - 2 = 89 +62 -2

= 151

8_murik_8 [283]

Answer:

Explanation:

The correct journal entry is shown below:

Equipment A/c Dr 700,000

      To Accumulated depreciation A/c $420,000

      To Retained earnings A/c $280,000

(Being the error is recorded and the remaining balance is credited to the retained earning account)

The depreciation expense would be

= (Original cost - residual value) ÷ (useful life)  

= ($700,000 - $0) ÷ (5 years)  

= ($700,000) ÷ (5 years)  

= $140,000  

For three years, the depreciation would be

= $140,000 × 3 years

= $420,000
