Chapter 10.1, Problem 4E

S&P 500 Stocks The data for Exercises 1 -4 consist of a random sample of 20 companies that were part of the S&P 500 and information was current as of March 7, 2017. For each variable, (a) group the data as indicated; (b) prepare a frequency distribution with columns for intervals and frequencies; (0) construct a histogram. (See Examples 1 and 2.) (Data from: data.okfn.org.)

The variable is market capitalization (in billions of dollars).

2. Let Y₁,……., Y be a random sample with common mean μ and common variance σ². Use the CLT to write an expression approximating the CDF P(Ỹ ≤ x) in terms of µ, σ² and n, and the standard normal CDF Fz(·).

3. We'd like to know the first time when the population reaches 7000 people. First, graph the function from part (a) on your calculator or Desmos. In the same window, graph the line y = 7000. Notice that you will need to adjust your window so that you can see values as big as 7000! Investigate the intersection of the two graphs. (This video shows you how to find the intersection on your calculator, or in Desmos just hover the cursor over the point.) At what value t> 0 does the line intersect with your exponential function? Round your answer to two decimal places. (You don't need to show work for this part.) (2 points)

Suppose the planet of Tattooine currently has a population of 6500 people and an annual growth rate of 0.35%. Use this information for all the problems below. 1. Find an exponential function f(t) that gives the population of Tattooine t years from now. (3 points)
