Answer:

a. 2.13. b. (30.53, 34.79). c. The mean prices for two in mid-range restaurants in Hong Kong are relatively less than those in Tokyo restaurants.

Explanation:

The size of the sample is 42 and the mean of the sample is ∑x_{i}n = 32.66 and the standard deviation of the sample (σ) is √[∑(x_{i}-μ)^2 - 1] = √46.6092 = 6.8271

a. α = 1 - (95/100) = 0.05; α/2 = 0.025; the degree of freedom = n-1 = 42-1 = 41; tα/2 = t0.025 = 2.02. Thus, the error margin = (tα/2)*(σ/√n) = 2.02*(6.83/√42) = 2.1279

b. Lower level limit = 32.66 - 2.1279 = 30.5321; Upper level limit = 32.66+2.1279 = 34.7879. The interval estimate = (mean± margin of error) = (30.53, 34.79).

c. The mean prices for two in mid-range restaurants in Hong Kong are relatively less than those in Tokyo restaurants.

miv72 [106K]

Answer:

Net income for the year = $257,000

Explanation:

Retained earnings for the year= Net income - dividends paid.

Since no dividends were paid, retained earnings for the year = net income for the year. At the end of each accounting period, retained earnings are reported on the balance sheet, and the retained profits for the year are added to the beginning balance of retained earnings, to give a cumulative ending balance of  $2,499,000.

therefore retained earnings for the year = ending retained earnings balance  - beginning retained earnings balance = $2,499,000.-$2,242,000= $257,000.

Net income for the year is  thus =  $257,000 since no dividends were paid.

Parton Company, a manufacturer of snowmobiles, is operating at 80% of plant capacity. Parton's plant manager is considering maki
ira [324]

Answer:

The answer is: a

Explanation:

The Parton Company has a 'make or buy' decision. This decision involves analysing the incremental costs associated with each option. Incremental costs are costs incurred as a result of producing one more unit of a product. If the excess capacity can be utilised to produce the headlights at a lower cost than the cost of acquiring the headlights from an external supplier, then the company should produce the headlights.  

The Parton Company incurs $12.80 per headlight purchased from the external supplier. Added to this cost, are the existing costs of operating below plant capacity. If making the headlights in the manufacturing plant yields a positive contribution to fixed costs, then the Parton company should produce the headlights in the manufacturing plant.

By producing the headlights, the Parton company gains a contribution to fixed costs of $1.03 per headlight.

Foregone purchase costs from supplier:                          $12.80

Incurred costs (directly) from production:                        ($11.77)

Direct materials                                                                     ($4.45)

Direct Labour                                                                         ($3.45)

Manufacturing Overheads: $(6.45*0.6)                               <u>($3.87)</u>

Net gain per headlight                                                           <u> </u><u>$1.03</u>

sesenic [268]

Answer: Decrease in the short run aggregate supply. increase in long run aggregate supply

Explanation:

assuming the wage stays constant in the short run (price of labour), an increase inflation/general prices will lead to a decrease in the Supply of labour because the current wage is no longer enough to cover the same number of goods people used to buy which will then increase Unemployment. The Labor market will experience a situation where inflation and unemployment are increasing at the same time

The Supply of Labour will increase in the Long run because the wage price will have sufficient time to adjust and increase to a new equilibrium level. .an increase in wage price will increase the quantity of supplied.
