A card store set up a table at the front of the store for a survey with an employee at the table. Every customer who came into the store was asked to fill out a survey. The purpose of the survey was to determine if customers would prefer, and pay the extra charge, for postage-paid envelopes. Would this be an appropriate sampling technique?
A.
No, because the sample is not random and is dependent on customers stopping at the table.

B.
Yes, because the sample is fairly small, random, and representative of customers who purchase sympathy cards.

C.
Yes, because the sample is fairly large, random, and representative of the population.

D.
No, because the sample is too large and should have online surveys instead of a table survey.

B

Explanation:

i think its pretty reasonable

well for some you have to do on your own on a paper but yeah

sentences vary by structure as well as by function. there are compound, complex, and compound-complex sentences.

simple sentence

i like to read.

a simple sentence has one independent clause.

compound sentence

i like to read, and i also like to write.

a compound sentence includes more than one independent clause, connected by a coordinating conjunction (and, but, for, nor, or, so, or yet).

complex sentence

i prefer to read books that are bestsellers.

a complex sentence includes one independent clause and one or more dependent clauses. (a dependent clause is one that cannot stand alone.) types of dependent clauses include relative clauses (i kicked the boy who pinched me), adverb clauses (i am going home now because i have a curfew), and noun clauses (i don't know what to do next).

compound-complex sentence

although i prefer to read current bestsellers, i do like to read old agatha christie mysteries, and i also like some 20th-century science fiction.

compound-complex sentences take a bunch of clauses (multiple independent clauses, and one or more dependent clauses) and toss them together like a salad. although these sentences take practice to write in a grammatically correct fashion, they can hold a tremendous amount of meaning, and are common in academic writing.
