Answer:

The Confidence Interval(CI) is calculated as (0.043, 0.257).

The steps and expanation is shown below.

Explanation:

The formula for a Confidence Interval(CI) for a population proportion is given as

p + z*[Sqrt(p(1 - p))/n]

Or

p - z*[Sqrt(p(1 - p))/n],

p is the sample proportion, n is the sample size, and z* is the appropriate value from the standard normal distribution for your desired confidence level. The following table shows values of z* for certain confidence levels.

For the 98% Confidence Interval, z*–value = 2.33

p = 9/60 = 0.15, confidence level z* = 2.33( From the standard table)

0.15 + 2.33[Sqrt(0.15(1 - 0.15))/60]

OR

0.15 - 2.33[Sqrt(0.15(1 - 0.15))/60]

0.15 + 0.107 or 0.15 - 0.107

Confidence Interval is

(0.043, 0.257)

Answer:

= (0.043 , 0.257)

Explanation:

p = 9/60 = 0.15

Z score for 98% confidence interval = Z0.01 = 2.33

The Confidence interval = (p + Z0.01 * sqrt(p * (1 - p) / n))

= (0.15 + 2.33 * sqrt(0.15 * (1 - 0.15) / 60))

= (0.15 + 0.107)

= (0.043 , 0.257)

The duel between Aaron Burr and Alexander Hamilton was the result of:
earnstyle [38]

Answer:

Option D: Burr's belief that Hamilton had slandered him.

Explanation:

The duel stemmed from a history of animosity between both men over the years. The existing personal animosity and personal bitterness between both individuals came to a head in the run-up to the governorship election in New-York in 1804.

The Albany Registrar published a letter sent from Charles Cooper to senator Philip Schuyler which referenced a statement made by General Hamilton describing Colonel Burr as being a dangerous and despicable human being incapable of running a government.

The ensuing duel was as a result of this defamation.

the second option

Explanation:

Present value is the sum of discounted cash flows

Present value can be calculated using a financial calculator

first option

Cash flow in year 1 and 2 - $85,000

1 = 7

PV = $153,681.54

Second option

Cash flow in year 0 = $20,000

Cash flow in year 1 and 2- $74,000

I = 7

PV =  $153,793.34

the pv of the second payment is higher than the first so the seconf would be choosen

To find the PV using a financial calculator:

1. Input the cash flow values by pressing the CF button. After inputting the value, press enter and the arrow facing a downward direction.

2. after inputting all the cash flows, press the NPV button, input the value for I, press enter and the arrow facing a downward direction.  

3. Press compute

Minneapolis, MN has a CPI of 173. Anchorage, AK has a CPI of 226. How does the purchasing power of someone in Minneapolis earnin
nikdorinn [45]

Answer:

The answer is: C) The person living in Anchorage has $50.80/CPI more than the person in Minneapolis.

Explanation:

The Consumer Price Index (CPI) weighs the average prices of a basket of consumer goods and services. So the higher the CPI, the more expensive it is to purchase goods or services in that place.

The purchasing power of someone living in Minneapolis and earning $42,500 is $245.66/CPI; for someone living in Anchorage and earning $67,000 is $296.46/CPI. The difference between them is $296.46/CPI minus $245.66/CPI equals $50.80/CPI.

The person living in Anchorage has $50.80/CPI more than the person in Minneapolis.
