Work out the mean for the data set below: 67005, 67004, 67006, 67006, 67005, 67005, 67004, 67005

General Formulas and Concepts:

Statistics

Step-by-step explanation:

Step 1: Define

Total:   67005 + 67004 + 67006 + 67006 + 67005 + 67005 + 67004 + 67005

Amount:   8 numbers

Step 2: Find mean

And we have our final answer!

Money deposited in US savings account = 425$

Explanation:

 Let deposit made in US, 7/4 Bank, and Catch Bank be a,b and c respectively.

 We have total deposit =  $2125

        a + b + c = 2125   Equation 1

 She will deposit 4 times as much into catch bank as 7/4 Bank because they offer a higher interest rate

        c = 4 b   Equation 2

She also expects the Bank of the US deposit to be 25% of the total of the other two deposits

       a = 0.25 ( b + c )

       4 a = b + c   Equation 3

Equation 1 + Equation 3,

   a + b + c + 4 a = 2125 + b + c

                      5 a = 2125

                          a = 425$

 So money deposited in US savings account = 425$
