Ancestry and Region. The U.S. Census Bureau collects information on the U.S. population by ancestry and region of residence and publishes the results in American Community Survey. According to that document, 18% of the population resides in the Northeast. a. If ancestry and region of residence are not associated, what percentage of Americans of Irish ancestry would reside in the Northeast? b. There are roughly 37 million Americans of Irish ancestry. If ancestry and region of residence are not associated, how many Americans of Irish ancestry would reside in the Northeast? c.

Code Churn. Code Churn is a common metric used to measure theefficiency and productivity of software engineers and computerprogrammers. It's usually measured as the percentage of aprogrammer's code that must be edited over a short period of time. Programmers with higher rates of code churn must rewrite code moreoften because of errors and inefficient programming techniques. Thefollowing table displays sample information for 10 computerprogrammers. a. Use the data in the table above and the relative frequencymethod to determine probabilities that a randomly selected line ofcode will need to be edited for each programmer.b. If you randomly select a line of code from Liwei, what is theprobability that the line of code will require editing?c. If you randomly select a line of code from Sherae, what is the probability that the line of code will not require editing?d. Which programmer has the lowest probability of a randomlyselected line of code requiring editing? Which programmer has…
