Proposition statements are subsets of statements..... proposition statements are statements which are either true or false but both are not acceptable.
1) Evert student passed csci-4140 last year. This is declarative statement. so this is not proposition statement.
2) He is very Handsome (It may be true or false statement) so this is not proposition statement.
3) 64 = 2^6 Yes this is true...2 power 6 is 64(true) So so this is proposition statement.
4) x+2 =6 ....It depends upon x value..so so this is not proposition statement.
5) If you touch fire, you will not be burnt. It is mixup of question and declarative statement. so this is not proposition statement

line whether the sample described below is a simple random sample. In the last year, 144,888 adults paid taxes in a county. A researcher plans to conduct a survey of 1000 of those taxpayers. After obtaining a list of those who paid taxes, he numbers the list from 1 to 144,888, and then he uses a computer to randomly generate 1000 numbers between 1 and 144,888. His sample consists of the taxpayers corresponding to the selected numbers. Does this sampling...

As a student you have probably noticed a curious phenomenon. In every class, there are some students who zip through exams and turn their papers in while everyone else is still working. Other students continue working until the very last minute. Have you ever wondered what grades these students get? Are the students who finish first the best in the class or are they simply conceding failure? To answer this question, we carefully observed a recent...

I. Fused Sentence and Comma Splice Errors: The following groups of words contain comma splice and fused sentence errors. Above the incorrect sentence, indicate by labelling it with the correct initials the nature of the error (comma splice – write CS – or fused sentence – write FS), and then write a correctly revised version of the sentence in the space provided, using a variety of techniques and sentence structures. 1.
