Question
Chapter 9, Problem 13E
To determine
To create:
A script that will read from a file x and y data points in the following format:
x 0 y 1
x 1.3 y 2.2
| Year | Population |
| 1920 | 4021 |
| 1940 | 8053 |
| 1960 | 14994 |
| 1980 | 9942 |
| 2000 | 3385 |
The format of every line in the file is the letter ‘x’, a space, the x value, space, the letter ‘y’, space, and the y value. First, create the data file with 10 lines in this format. Do this by using the Editor/Debugger, then File Save As xypts.dat. The script will attempt to open the data file and error-check to make sure it was opened. If so, it uses a for loop and fgetl to read each line as a character vector. In the loop, it creates x and y

You want to obtain a sample to estimate the proportion of a population that possess a particular genetic marker. Based on previous evidence, you believe approximately p∗=11% of the population have the genetic marker. You would like to be 90% confident that your estimate is within 0.5% of the true population proportion. How large of a sample size is required?n = (Wrong: 10,603)
Do not round mid-calculation. However, you may use a critical value accurate to three decimal places.
