The margin of error of the random selection is 0.29
The given parameters are:
--- the sample size
--- the standard deviation
--- the mean
--- the confidence level.
The margin of error (E) is calculated as follows:

So, we have:


The z-value for 90% confidence level is 1.645.
Substitute 1.645 for z


Take square roots

Multiply

Approximate

Hence, the margin of error is 0.29

Answer:
The total monthly mortgage payment for the house is $975.63
Step-by-step explanation:
The principle amount is $175000
80% of 175000 is =
= $140000
20% of 175000 is =
= $35000
Emi formula is :

For 1st part:
p = 140000
r = 4.75/12/100=0.00395
n = 
Putting values in formula we get

= $729.508
For 2nd part:
p = 35000
r = 7.525/12/100=0.00627
n = 
Putting values in formula we get

= $245.301
Adding both the monthly payments:
dollars
This is closest to option A.
So, option A is the answer.
And for 30 years the mortgage payment will be =
dollars
