The overall distance traveled by a golf ball is tested by hitting the ball with Iron Byron, a mechanical golfer with a swing that is said to emulate the legendary champion, Byron Nelson. Ten randomly selected balls of two brands are tested and the overall distance measured. Assume that the variances are equal. The data follow: Brand 1: 280 295 287 271 283 271 279 275 263 267 Brand 2: 270 236 260 265 273 281 271 270 263 268...

Code is in C# Your instructor would like to thank to Marty Stepp and Hélène Martin at the University of Washington, Seattle, who originally wrote this assignment (for their CSE 142, in Java) This program focuses on classes and objects. Turn in two files named Birthday.cs and Date.cs. You will also need the support file Date.dll; it is contained in the starter project for this assignment. The assignment has two parts: a client program that uses Date objects, and a...
