Answer:

option  b is correct

Normal with a mean of $5.25 and a standard error of $0.28

Explanation:

Given data

mean = $5.25

standard deviation SD = $2.80

sample n = 100

to find out

sampling distribution

solution

we will find here first mean error that is

standard error = SD/ √n

put here value n and SD

standard error = 2.80 /√100

standard error = 0.28

and we know here that by central limit theorem that is state that sample distribution of sample mean is approximate normally distribute with Standard error and mean so

mean with normal is 5.25

Hence

option  b is correct here

Normal with a mean of $5.25 and a standard error of $0.28

The operations vice president is adjusting the production quantities for the upcoming month of March for the coal company. Last
12345 [234]

Answer:

The correct answer is letter "B": Increase output and hire more workers.

Explanation:

According to the supply law, if the price increases so will the quantity supplied and if the price decreases the same will happen with the quantity supplied. We could say that the relationship between price and quantity supplied is directly proportional.

In the example, <em>as the price of coal increased so will the quantity supplied</em>. <em>If there is to be more supply the output should be higher which is likely to be interpreted in a need for more employees</em>.

Shondee Corporation uses the lower of cost or market and FIFO inventory methods. At the end of 2018, the FIFO cost of the ending
Assoli18 [71]

Answer:

reported as income for all three years   is $7,000

Explanation:

given data

cost of the ending inventory = $181,000

market value  inventory =  $160,000

to find out

Shondee Corporation must add income

solution

we get here Income per year that is

Income per year = (Value under FIFO Method - Value Under Cost Method ) ÷ Number of year      ..............................1

put here value we get

Income per year = \frac{181000 - 160000}{3}

Income per year =   \frac{21000}{3}

Income per year =  $7000

so reported as income for all three years   is $7,000

Keystone predators can maintain species diversity in a community if they
Vikki [24]

Answer:

The options are given below:

A) competitively exclude other predators.

B) prey on the community's dominant species.

C) allow immigration of other predators.

D) reduce the number of disruptions in the community.

E) prey only on the least abundant species in the community.

the correct option is B

Explanation:

Keystone species refers to a predator which prevents a particular herbivorous species from wiping out the dominant plant species. If the number of prey are low, the keystone predators can be less abundant and still be effective. Keystone species have a disproportionately large effect on its environment relative to its abundance.

Therefore, by preying on a community's dominant species, keystone predators help to maintain the species diversity in the community, because they ensure that the dominant predators do not totally wipe out the various organisms present in the ecosystem.

Explanation:

Data provided in the question  

Petty cash fund balance = $500

Remaining cash balance = $105

Vouchers for miscellaneous expenses = $400

Sp by considering the above information, the effect would be and the balance would be  

= Petty cash fund balance - remaining cash balance

= $500 - $105

= $395
