Answer: the interest on the loan is $39.38
Step-by-step explanation:
The formula for determining simple interest is expressed as
I = PRT/100
Where
I represents interest paid on the loan.
P represents the principal or amount taken as loan
R represents interest rate
T represents the duration of the loan in years.
From the information given,
P = $350
R = 4.5%
There are 12 months in a year. Converting 30 months into years, it becomes
30/12 = 2.5. so
T = 2.5 years
Therefore
I = (350 × 4.5 × 2.5)/100
I = $39.38
Using Z-test:
The Z score is:
Z = (198 - 200) / 23 = -0.087
Assuming normal distribution and from the z table, the probability based on the Z score is
p = 0.47 or 47%
Therefore, there is a probability of 47% that the 15 elephants will have a mean weight of 198 lbs.
