Answer:

$18.74

Explanation:

the margin of error for a 95% confidence level = Z x (σ / √n)

  • Z for a 95% confidence level = 1.96
  • standard deviation (σ) = $160
  • sample size (n) = 280

the margin of error for a 95% confidence level = 1.96 x ($160 / √280) = 1.96 x ($160 / 16.733) = 1.96 x $9.56 = $18.74

You are ready to buy a house, and you have $20,000 for a down payment and closing costs. Closing costs are estimated to be 4% of
Bess [88]

Answer:

So we can offer for the house $180119.95

Explanation:

Monthly income =$4000

Monthly mortgage payment allowed (P)= 25% of 4000= $1000

Interest rate per month (i)= 0.5%

Number of months in total (n)= 30*12= 360

Maximum loan affordable = P*(1-(1/(1+i)^n))/i

=1000*(1-(1/(1+0.5%)^360))/0.5%

=$166791.61

Closing cost is 4% of loan value = 166791.61*4% =$6671.66

Balance Amount left for down payment = 20000-6671.66

=$13328.34

It means we can pay $6671.66 for closing cost of Loan and $13328.34 for down payment.

Cost of house paid maximum = Down payment + Affordable loan

=13328.34+166791.61

=$180119.95

So we can offer for the house $180119.95
