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

What would happen to the body if the body temperature continue to decrease during the 10th hour instead of leveling off
skad [1K]

Answer:

there body would over heat

Explanation:

Hypothermia occurs when the core body temperature drops below 35°C, ie it is unintentional excessive heat loss. According to the graph shown in the question, hypothermia would happen if body temperature continued to decrease over the tenth hour rather than stabilize.

The core temperature of the human body should be between 36.5ºC and 37.5ºC. Below this threshold, various symptoms begin to appear, from cold to death. When there is a sudden drop in body temperature, the nerve endings detect the low temperature and immediately the body begins to perform vasoconstriction (downsizing) of the blood vessels, especially the skin, in order to decrease heat loss and stabilize the internal temperature. This is why the skin gets cold.

vovikov84 [41]

Answer:

1. What would depreciation expense be for year 3 under the straight-line method?

= ($480,000 - $30,000) / 8 = $56,250

same depreciation expense for every year

2. What would depreciation expense be for year 3 under the double-declining balance method?

depreciation year 1 = 2 x 1/8 x $480,000 = $120,000

depreciation year 2 = 2 x 1/8 x $360,000 = $90,000

depreciation year 3 = 2 x 1/8 x $270,000 = $67,500

3. What is the first year in which depreciation expense under the straight-line method is higher than under the declining balance method?

under double declining method

depreciation year 4 = 2 x 1/8 x $202,500 = $50,625

In year 4, depreciation expense wil be higher using the straight line method.

4. Assume TarMart uses the straight-line depreciation method for its equipment. Also assume that at fiscal year-end 2020, TarMart sold the equipment purchased at the beginning of fiscal year 2016 for $200,000 cash. Prepare the journal entry to record the sale of the equipment at year-end 2020.

Dr Cash 200,000

Dr Accumulated depreciation - equipment 225,000

Dr Loss on sale of equipment 55,000

    Cr Equipment 480,000

Explanation:

purchase cost $480,000

useful life 8 years

salvage value $30,000

Wassamatta University is considering resigning its minimum qualifications for professors from possessing a master's degree to po
bulgar [2K]

Answer:

c. shift the supply curve of professors to the left ceteris paribus

Explanation:

Labour Supply curve shows the labour hours,  employees or workers are willing & able to supply, at given wage rates during a period of time.

The curve is upward sloping due to positive relationship between wage rates & labour. As more labour is supplied at higher wage rate, less labour is supplied at lower wage rates.

Change in any other factor other than wages, changes (shifts) the supply curve. Factor increasing labour supply shifts the supply curve rightwards. Factor decreasing labour supply shifts the supply curve leftwards.

The case given : as increase in the minimum qualifying eligibility for the job, decreases the number of people who are 'able' to supply labour as per the criteria. So, it decreases labour supply & shifts the curve leftwards.

A portfolio is composed of two securities, Stock X and Stock Z. Stock X has a standard deviation of returns of 35%, while Stock
emmainna [20.7K]

Answer:

Portfolio SD = 0.18439 or 18.439%

Explanation:

The standard deviation of a stock or a portfolio is the measure of the total risk contained in the stock or portfolio. Risk can be defined as the volatility of the stock returns. To calculate the standard deviation of a two stock portfolio, we use the attached formula.

If the weight of stock x is 40%, the weight of stock y will be 1 - 40% = 60%

SD = √(0.4)^2 * (0.35)^2 + (0.6)^2 * (0.15)^2 + 2 * 0.4 * 0.6 * 0.25 * 0.35 * 0.15

SD = 0.18439 or 18.439%

Bill's employer offers a new health insurance benefit that covers preventive and cosmetic dental services, including orthodontic
Artyom0805 [142]

The given statement is FALSE.

Explanation:

This is an example of adverse selection.

Adverse selection applies to a case in which the purchasers and distributors of the insurance policy don't have the same details at their fingertips. A typical definition of health insurance is where a person wants to learn if he is ill and in need of health coverage before paying for a health insurance package.

Examples of adverse selection in life insurance involve cases when a person with a high-risk career, such as a racing car driver or someone dealing with weapons, obtains a life insurance policy without the need for an insurance provider realizing that they have a risky position.
