Answer: $ 40331.781 (Approx)
Step-by-step explanation:
Let Monica pay off $ x in 12 years,
Thus, for 12 years, his present value, PV = $ x
Given, APR of the loan = 8.4% = 0.084
Thus, the monthly rate of the loan, r = 0.084/12 = 0.007
The number of period in 12 years, n = 144
And, the monthly payment, P = $ 990.39
Thus, by the formula,
Thus, He pay off $ 89668.2185624 of the original amount of the loan.
⇒The amount of loan left after 12 years
= 130,000 - 89668.2185624
=40331.7814376 ≈ $ 40331.781
Answer:
Value of test statistics = 2.30
Step-by-step explanation:
We are given that for a sample of 35 items from a population for which the standard deviation is 20.5, the sample mean is 458.
Also, Null Hypothesis, :
= 450
Alternate Hypothesis, :
450
The test statistics that will be used here is One sample t-test statistics;
T.S. = ~
where, = sample mean = 458
s = sample standard deviation = 20.5
n = sample of items = 35
So, test statistics = ~
= 2.30
Therefore, the value of test statistics is 2.30 .
