Explanation:

Step1: Sum all populations

First, we add up all the population values:
\(1,449,157 + 1,021,052 + 9,944,673 + 2,991,373 + 1,948,079 + 1,372,729 + 1,970,253 + 2,936,649 + 1,701,992\)

Let's calculate step by step:
\(1,449,157 + 1,021,052 = 2,470,209\)
\(2,470,209 + 9,944,673 = 12,414,882\)
\(12,414,882 + 2,991,373 = 15,406,255\)
\(15,406,255 + 1,948,079 = 17,354,334\)
\(17,354,334 + 1,372,729 = 18,727,063\)
\(18,727,063 + 1,970,253 = 20,697,316\)
\(20,697,316 + 2,936,649 = 23,633,965\)
\(23,633,965 + 1,701,992 = 25,335,957\)

Step2: Count number of counties

There are 9 counties (Alameda, Contra Costa, Los Angeles, Orange, Riverside, Sacramento, San Bernardino, San Diego, Santa Clara).

Step3: Calculate the mean

The mean is the total sum divided by the number of counties:
\(\text{Mean} = \frac{25,335,957}{9}\)

Calculating this division:
\(25,335,957 \div 9 \approx 2,815,106.333...\)

Step4: Round to nearest whole number

Rounding \(2,815,106.333...\) to the nearest whole number gives \(2,815,106\).

Answer:

2815106
