Answer:

2257.50

Step-by-step explanation:

B=p(1+r)^t

p= principal amount= $7000 in the saving account

r= interest rate= 15%= .15

t- number of years = 2

B= 7000(1+.15)^2

B= 7000(1.15)^2

B= 7000(1.15)(1.15)

B= 9257.50

She has a total of 927.50 dollars in the account after two years. To find out how much of that is interest we take the Balance and subtract what she invested.

B-p= 9257.50-7000= 2257.50 earned in interest.

When do you reject the null hypothesis?
Nimfa-mama [501]

You reject the Null Hypothesis when you have a small P-Value. Here is an example! Also we never accept the null hypothesis, think of it like this if we bring someone to court you wouldn't say their innocent of a crime, you only know that if they do not get convicted of the crime they are not guilty in the eyes of the law. Same thing applies here, since there could be several answers that satisfy our assumptions made, we can not be certain that 1 of those assumptions is the REAL answer it's just AN answer.
