Answer:
Simple interest at 2.1%
Step-by-step explanation:
If you had $200 to start
Simple would be $200 x 2.1% = $4.2
$4.2x3 years = $12.60
Total money after 3 years $212.60
Compound would be $200 x 2.7% = $5.40 1st year
$205.40 x 1.4% = $2.8756 (2.88 rounded) 2nd year
$208.28 x 1.4% = $2.9159 (2.92 rounded) 3rd year
3 years total = $211.20
$212.60 greater then $211.20

Answer:
The combined standard deviation is 1.58114.
Step-by-step explanation:
The formula to compute the combined standard deviations of two different data sets is:

Here
is the combined mean given by:

It is provided that the sample size is same for both the data sets, i.e.
Compute the combined mean as follows:

Compute the combined standard deviation as follows:

Thus, the combined standard deviation is 1.58114.
