The monthly payment amount is $860.25.
Step-by-step explanation:
Step 1; The bank offers an amount of $195,000 with an APR of 5.3%. This means that the family must pay 5.3% of the $195,000 every year for 30 years. To calculate we must determine how much 5.3% of $195,000 is. To do that we make 5.3% a fraction by dividing it by 100 and multiplying it with the amount.
5.3% of $195,000 = × $195,000 = 0.053 × $195,000 = $10,335 per year.
Payment owed for 30 years = Payment owed a year × 30
= $10,335 per year × 30 = $310,050 for 30 years.
Step 2; To find the monthly payments we need to know how many months are in a 30 year period. Months in 30 years = 30 × 12 months = 360 months. The monthly payment is, therefore, payment owed in 30 years divided by the months in that 30 year period.
Monthly payment = $10,335 / 360 = $ 861.25.
So the family must pay a monthly payment of $861.25 for 30 years.

Answer:
We need a sample size of at least 1161.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of , and a confidence level of
, we have the following confidence interval of proportions.
In which
z is the zscore that has a pvalue of .
The margin of error for the interval is:
For this problem, we have that:
90% confidence level
So , z is the value of Z that has a pvalue of
, so
.
How large a sample should she take?
We need a sample size of at least n.
n is found when
So
Rounding up
We need a sample size of at least 1161.
