Nat2105 [25]

Answer:

  $4127

Step-by-step explanation:

The amortization formula is good for finding this value.

  A = P(r/12)/(1 -(1 +r/12)^(-12t))

where P is the amount invested at rate r for t years.

  A = $600,000(0.055/12)/(1 -(1 +0.055/12)^(-12·20)) = $4127.32

You will be able to withdraw $4127 monthly for 20 years.

Find the margin of error for a 90% confidence interval when the standard deviation is LaTeX: \sigma= 50????=50 and LaTeX: n = 25
Murrr4er [49]

Answer:

The margin of error  for a 90% confidence interval is 16.4

Step-by-step explanation:

We are given the following in the question:

Sample size, n = 25

Standard deviation = 50

z_{critical}\text{ at}~\alpha_{0.10} = \pm 1.64

Margin of error =

z_{critical}\times \dfrac{\sigma}{\sqrt{n}}

Putting the values, we get,

1.64\times \dfrac{50}{\sqrt{25}} = 16.4

Thus, the margin of error  for a 90% confidence interval is 16.4
