Suppose that in a certain community, 40% of the residents would answer "yes" to the question, "do you know the names of at least

five other people who live on your block?" suppose you plan to take a random sample of 100 people from this community and calculate the proportion of people in your sample whose response to this question is "yes".

Answer:

The proportion of people in your sample whose response is yes=40 people

Explanation:

<em>Step 1: Determine the statistical proportion that will say yes</em>

Proportion=40%=40/100=0.4

<em>Step 2: Determine the proportion in the sample that will say yes</em>

The proportion in the sample can be expressed as;

P=S×Z

where;

P=proportion in the sample

S=statistical proportion

Z=sample size

In our case;

P=unknown to be determined

S=40%=40/100=0.4

Z=100

replacing;

Proportion in the sample=0.4×100=40

The proportion of people in your sample whose response is yes=40 people

Governmental financial reporting should provide information to assist users in which situation?
trasher [3.6K]

Answer: making economic, social, and political decisions and also

assessing whether current-year citizens received services but if part of the payment burden was shifted part to future-year citizens.

Winona and Hubert need to decide which one of them will take time off from work to complete the rather urgent task of shearing t
Flauer [41]

Answer: Winona has the lowest opportunity cost of completing the task.

Explanation:

Based on the information given in the question, the opportunity cost will be calculated as:

= Earnings per hour × Hours taken to complete the task

Therefore, for Winona, the opportunity cost will be:

= 1 × $200.

= $200.

For Hubert, the opportunity cost will be:

= 9 × $25

= $225

Therefore, based on the calculation above, Winona has the lowest opportunity cost of completing the task.

Repair calls are handled by one repairman at a photocopy shop. Repair time, including travel time, is exponentially distributed,
wolverine [178]

Answer:

the average number of customers awaiting repairs = 0.30

the system utilization = 42

the amount of time that the repairman is not out on a call is  = 4.64 hours

the probability of two or more customers in the system = 0.1764

Explanation:

Given that :

Repair time, including travel time =  mean of 1.6 hours per call.

Requests for copier repairs = mean rate of 2.1 per eight-hour day

i.e mean rate R = 2.1/day

Time = 8 hours

thus; mean rate μ = 8 hours/ 1.6 hours = 5

(a)

Let the average number of customers awaiting repairs be I_i :

I_i = \dfrac{R^2}{\mu (\mu-R)}

I_i = \dfrac{2.1^2}{5 (5-2.1)}

I_i = \dfrac{4.41}{5 (2.9)}

I_i = \dfrac{4.41}{14.5}

\mathbf{I_i = 0.30}

the average number of customers awaiting repairs = 0.30

(b) Determine system utilization.

The system utilization is determined as follows:

\delta = \dfrac{R}{\mu}

\delta = \dfrac{2.1}{5}

{\delta = 0.42}

\mathbf{\delta = 42}

(c) The amount of time during an eight-hour day that the repairman is not out on a call is calculated as :

Percentage of Idle time = 1 - \delta

Percentage of Idle time = 1 - 0.42

Percentage of Idle time = 0.58

However during an 8 hour day; The amount of time that the repairman is not out on a call is = 0.58 × 8 = 4.64 hours

(d)

the probability of two or more customers in the system by assuming Poisson Distribution is:

P(N ≥ 2) = 1 - (P₀+ P₁)

where;

P₀ = 0.58

P₁ = 0.58  × 0.42 = 0.2436

P(N ≥ 2) = 1 - ( 0.58 + 0.2436)

P(N ≥ 2) = 1 - 0.8236

P(N ≥ 2) = 0.1764

Thus; the probability of two or more customers in the system is 0.1764

Downing Company issues $4,000,000, 8%, 5-year bonds dated January 1, 2020 on January 1, 2020 (ten periods). The bonds pay intere
zlopas [31]

Answer:

$4,525,123.84

Explanation:

The computation of the proceeds from the issuance of the bond is shown below:

Given that

Face Value of Bonds = $4,000,000

Annual Coupon Rate = 8%

So, Semiannual Coupon Rate = 4%

So, Semiannual Coupon = 4% × $4,000,000

= $160,000

Time to Maturity = 5 years

So, Semiannual Period = 10

And,

Annual Interest Rate = 5%

So, Semiannual Interest Rate = 2.5%

Now the proceeds from the issuance of the bond is

= $160,0000 × PVIFA(2.5%, 10) + $4,000,000 × PVIF(2.5%, 10)

= $160,000 × 8.752064  + $4,000,000 × 0.78120

= $1,400,330.23  + $3,124,793.61

= $4,525,123.84
