The 95% confidence interval will be wider than the 90% confidence interval.

In statistics, the likelihood that a population parameter will fall between a set of values for a certain percentage of the time is referred to as a confidence interval. Analysts frequently employ confidence ranges that include 95% or 99% of anticipated observations. Therefore, it may be concluded that there is a 95% likelihood that the real value falls within that range if a point estimate of 10.00 with a 95% confidence interval of 9.50 - 10.50 is derived using a statistical model.

  • The level of certainty or uncertainty in a sampling process is measured by confidence intervals.
  • Additionally, they are employed in regression analysis and hypothesis testing.
  • To determine statistical significance, statisticians frequently combine confidence intervals with p-values.
  • 95% or 99% confidence levels are most frequently used in their construction.

Answer:

Explanation:

A) Energy can be both a fixed cost and a variable cost for a company. This is due to the sense that energy in the form of fixed electricity bill even when no production takes place (telephone bill), a fixed cost and electricity bill when production takes place would be a variable cost

B) An increment in fixed cost will shift the ATC curve to the right while the MC curve would remain the same because MC is the change in variable cost as output increases and is not related to fixed cost.

C) Corn cost is a variable cost for ethanol producer as each unit of corn is used to produce ethanol and thus use of corn is reliant upon how much ethanol is produced. This makes corn a variable input dependent on the production of output, therefore, the cost of corn is variable.

D) An increment in the variable cost will shift the ATC curve to the right and individual MC curve to the right.

Consider an offer to supply 5 paintings per year to an art gallery in Rome for the next five years. The contract is exclusive, m
IceJOKER [234]

Answer:

I will accept the offer if the price per painting is $56,312.41 or higher.

Explanation:

We will calculate the present value of the other option which is, selling our painting as a freelancer.

C \times \frac{1-(1+r)^{-time} }{rate} = PV\\

C 315,000.00

time 5

rate 0.2

315000 \times \frac{1-(1+0.2)^{-5} }{0.2} = PV\\

PV $942,042.8241

Now, we subtract the signing bonus of 100,000

942,042.83 - 100,000 = 842,042.83

And solve for the annual proceeds from the painting we need to equalize the opportunity cost:

PV \div \frac{1-(1+r)^{-time} }{rate} = C\\

PV 842,042.83

time 5

rate 0.2

842042.83 \div \frac{1-(1+0.2)^{-5} }{0.2} = C\\

C  $ 281,562.03

Now, we divide by the 5 painting per year:

$281,562.03 per year / 5 painting per year = $56,312.41

What is the relationship between the alpha level, the size of the critical region, and the risk of a type i error?
quester [9]
Alpha level is a probability value that is used to define the concept of "very unlikely" in a hypothesis. This value determines he boundaries for the critical region, which is composed of the extreme sample values that are very unlikely to be obtained if the null hypothesis is true. Type I error is <span>when a researcher rejects a true null hypothesis.</span>
The relationship between the alpha level, the size of the critical region, and the risk of a type i error is the following: when the alpha level increases, the critical region increases and type I error increases.

Skysong, Inc. reports the following for the month of June. Units Unit Cost Total Cost June 1 Inventory 250 $5 $ 1,250 12 Purchas
ziro4ka [17]

Answer:

Weighted average unit cost =  $8.78

Explanation:

<em>The weighted average method of inventory determines the average cost per unit of inventory each time a new batch is received. or every new batch received the average cost per unit is re-computed by dividing the total value of stock by the outstanding number of units.</em>

The explanation is completed using calculation below:

Total value of stock = (250× $5)   +  (500×$9) + (375 × 11)  = $9,875

Total units of stock = 250 + 500 + 375 = 1,125  units

Weighted average unit cost = Total value of stock / total units of stock

                                        =  $9875 / 1125 units = $8.78

Weighted average unit cost =  $8.78
