First, we have to estimate the standard deviation

The MSE can be calculated as

The weighted sample size nh can be calculated as

The standard deviation then becomes

The z-value for a 99% confidence interval is z=2.58.
The difference between means is

Then the confidence interval can be constructed as

Answer: 200,000,000 or 2 million
Step-by-step explanation:
A unit rate is when you find a rate when one variable (or value) is equal to one.
