Based on the percentage of readers who own a particular make of the car and the random sample, we can infer that there is sufficient evidence at a 0.02 level to support the executive claim.

<h3>What is the evidence to support the executive's claim?</h3>

The hypothesis is:

Null hypothesis : P = 0.55

Alternate hypothesis : P ≠ 0.55

We then need to find the test statistic:

= (Probability found by marketing executive - Probability from publisher) / √( (Probability from publisher x (1 - Probability from publisher))/ number of people sampled

= (0.46 - 0.55) / √(( 0.55 x ( 1 - 0.55)) / 200

= -2.56

Using this z value as the test statistic, perform a two-tailed test to show:

= P( Z < -2.56) + P(Z > 2.56)

= 0.0052 + 0.0052

= 0.0104

The p-value is 0.0104 which is less than the significance level of 0.02. This means that we reject the null hypothesis.

The Marketing executive was correct.

Nadya [2.5K]

Answer: 18.8%

Explanation:

Simple rate of return on investment = Incremental net operating income / investment

Incremental net income = Operating savings - Annual cost

= 145,000 - 420,000/6 years

= $75,000

Net investment = Cost of new machine - salvage value of old

= 420,000 - 21,000

= $399,000

Return on investment = 75,000/399,000

= 18.8%

For each hypothetical scenario, indicate whether the tariff described is more likely a protective tariff or a revenue tariff.
LenaWriter [7]

Answer:

a. In response to concerns from business leaders, a legislator has designed a new tariff on raw materials used by many manufacturing firms. The legislator felt the new tariff was necessary based on input from the private sector that new discoveries of natural resources abroad would threaten to put domestic producers of raw materials out of business. To meet this goal, this tariff will charge $1,500 on every crate of the imported goods plus an additional 6% of the total value of the imported goods.

  • protective tariff since it is designed to protect domestic industries from competition of out of state producers. It is designed to increase the price of imported goods.  

b. In an effort to balance next year's budget, a senator has proposed a new tariff. She proposed the new tariff with a goal of raising a total of $100 million, To meet this goal, this tariff will charge $2,000 on every ton that is imported.

  • revenue tariff since its main purpose is to increase government revenue, not to protect domestic industries.

Cool Sky reports the following costing data on its product for its first year of operations. During this first year, the company
Monica [59]

Answer:

$91

Explanation:

Given the following information,

Direct materials per unit = $54

Direct labor per unit = $20

Variable overhead per unit = $6

Fixed overhead for the year = $462,000

For Absorption costing method, it includes all costs associated with production, including fixed and variable cost. The unit product cost is calculated using direct material, direct labor and total unitary manufacturing overhead.

Unitary cost = (Fixed overhead for the year / Units produced) + Direct materials per unit + Direct labor per unit + Variable overhead per unit

Unitary cost = ($462,000 / 42,000) + $54 + $20 + $6

Unitary cost = $11 + $54 + $20 + $6

Unitary cost = $91

Therefore, the product cost per unit is $91
