The mean and standard deviation of a random sample of 7 baby orca whales were calculated as 430 pounds and 26.9 pounds, respectively. Assuming all conditions for inference are met, which of the following is a 90 percent confidence interval for the mean weight of all baby orca whales?
Unit 7 Progress Check: MCQ Part A. Researchers have undertaken a long-term study of populations of rock pocket mice, Chaetodipus intermedius, in Arizona and New Mexico. Rock pocket mouse fur is either dark or light in color.
It aims to introduce the Polygon platform to the new problem setters, and guide them through the basic steps on creating a new problem from scratch. In the post, I have explained the concepts and practices that a problem setter need to know in order to use Polygon to prepare problems.
give mathematical reasons, and that you verify the needed conditions under which relevant theorems, properties, definitions, or tests are applied. Your work will be scored on the
The mission of Polygon is to provide platform for creation of programming contest problems. Polygon supports the whole development cycle: problem statement writing; test data preparing (generators supported) model solutions (including correct and wittingly incorrect) judging; automatic validation
The volume of a cylinder is equal to the height times the area of the circular base. The area of the circular base is equal to (pi) times the square of the radius. The code segment below is intended to compute and print the volume of a cylinder with radius r and height h.
