Answer: The expected population proportion that wants flexible working hours is between <u> 58%</u> and <u>62%.</u>

Step-by-step explanation:

The margin of error (E) is used to represent the level of accuracy of any random sample.

Confidence interval for population percentage (p):

 (p-E, p+E ) , where E is the margin of error ( in percentage.)

Given : The percentage of the sample respondents agreed that employees should have flexible working hours : p = 60%

The margin of error : E=  ± 2%

Then , the expected population proportion that wants flexible working hours is between : 60%-2% and 60% +2%

= 58% and 62%.

Hence, the expected population proportion that wants flexible working hours is between <u> 58%</u> and <u>62%</u>.

just add 2 to 60 
and subtract 2 from 60 to find the range of percents

A cylinder has a volume of 175 pie cubic units and a height of seven units what's the diameter
Debora [2.8K]
Πr²h=175
πr²*7=175
Divide both sides by 7
πr²=25
Divide both sides by π (3.14)
r²=7.96
Square root of 7.96=2.82
r=2.82
Diameter is 2r. 2.82*2
2.82*2=5.64

The Campbell Company is considering adding a robotic paint sprayer to its production line. The sprayer's base price is $1,020,00

1. The Year-0 net cash flow is -$1,061,500.

2. The net operating cash flows in Years 1, 2, and 3 are as follows:

Year 1: $288,750 ($386,000 x 1 - 0.25)

Year 2: $288,750 ($386,000 x 1 - 0.25)

Year 3: $288,750 ($386,000 x 1 - 0.25)

3. The additional Year-3 cash flow (i.e, the after-tax salvage and the return of working capital) is $468,750 {($599,000 x 1 - 0.25) + $19,500}.

4. The NPV of the project is ($13,139).

5. The machine should not be purchased because it does not yield a positive NPV.

<h3>What is the net present value?</h3>

The net present value (NPV) shows the difference between the present value of cash inflows and the present value of cash outflows over a period of time.

It is determined by calculating the present values of cash flows using their present value factors as below:

<h3>Data and Calculations:</h3>

Initial cash outlay = $1,061,500 ($1,020,000 + $22,000 + $19,500)

Salvage value = $599,000

Increase in net working capital = $19,500

Annual savings before tax = $386,000

Tax rate = 25%

Annuial savings after tax = $288,750 ($386,000 x 1 - 0.25)

<h3>Determination of Net Present Value (NPV):</h3>

Year      Cashflows        PV Factor     Present Value

0          -$1,061,500               1             -$1,061,500

1              $288,750          0.901           $260,164

2             $288,750          0.812          $234,465

3             $288,750          0.731            $211,076

3             $468,750          0.731          $342,656

Net present value                                -$13,139

Thus, the project should not be undertaken by The Campbell Company due to the negative NPV that it yields.
