Suppose a city with population 400,000 has been growing at a rate of ​6% per year. If this rate​ continues, find the population of this city in 20 years.

Describe in detail how you would construct a 95% confidence interval for a set of 30 data points whose mean is 20 and population standard deviation is 3. be sure to show that you know the formula and how to plug into it. also, clearly state the margin of error.

Add the fractions, and simply the result to lowest terms. 2/3 + 2/7= ?
