Hello, I am having trouble with this problem for my discrete math class. I have provided a snip below. **Problem 2.4**Let \( A \) and \( B \) be two sets with a finite number of elements. Show that the number of elements in \( A \cap B \) plus the number of elements in \( A \cup B \) is equal to the number of elements in \( A \) plus the number of elements in \( B \).

using the Venn Diagram we can show that nA∪B=nA+nB-nA∩B The number of elements in A∪B is given by…

It is harder to get into graduate programs in psychology or history? We randomly selected five institutions from among all U.S. institutions with graduate programs. The first number for each is the minimum GPA for applicants to the psychology doctoral program, and the second is for applicants to the history doctoral program. These GPAs were posted on the website of the well-known college guide company Peterson's. Wayne State University: 3.0, 2.75 University of Iowa: 3.0, 3.0 University of Nevada-Reno: 3.0, 2.75 George Washington University: 3.0, 3.0 University of Wyoming: 3.0, 3.0 1. The participants are not people, explain why it is appropriate to use a paired-samples t test for this situation.
That is the first answer I got and it was also marked as incorrect. I am not sure why. I also tried the rounded version and it didn't work.
Attempt 7 Researchers claim that women speak significantly more words per day than men. One estimate is that a woman uses about 20,000 words per day while a man uses about 7,000. To investigate such claims, one study used a special device to record the conversations of male and female university students over a four-day period. From these recordings, the daily word count of the 20 men in the study was determined. The table contains their daily word counts. 28,408 10,084 15,931 21,688 37,786 10,575 12,880 11,071 17,799 13,182 8,918 6,495 8,153 7,015 4,429 10,054 3,998 12,639 10,974 5.255 To access the complete data set, click the link for your preferred software format: Excel Minitab JMP SPSS TI R Mac-TXT PC-TXT CSV Crunchlt!
