A spectacular population increase has accompanied the west coast’s industrial revolution. The Portland metropolitan area showed a 31 per cent increase in population since 1940; the Seattle area shows an increase in population for the same period of 200,000; and an estimated 1,500,000 people have entered California since 1940. Since most industrial activity on the west coast is confined to the manufacture of aircraft and the construction of ships, sharp curtailment of employment is threatened in the post-war period. With a population increase of 14 per cent, California, for example, faces the problem of shifting 1,500,000 workers from war activities to civilian jobs after the war. . . .
The typical white defense migrant is a young man, twenty-five years of age or younger, married, from a small town or rural area in the Pacific Northwest, anxious to settle in the area, and primarily interested in industrial employment in the post-war period. A study made recently in the Kaiser yards in Portland indicates that only 23.6 per cent of the migrants expressed a definite intention to leave after the war; that only a very few have maintained economic ties elsewhere or have jobs to which they might return; that considerable numbers have purchased property in the area; that a majority have their families with them; and that 86 per cent must find new employment immediately after their present employment terminates.
Answer:
A. Response questions
Explanation
A free-response question is a type of question the responder creates an answer to instead of simply choosing a correct answer from the given list, which is the case with multiple-choice questions. Forms of free-response questions are short-answer questions (such as your question), essay questions, and mathematics problems.
A matching question consists of two lists of related words, phrases, pictures, or symbols. Each option in one list is paired with at least one option belonging to the other list.
Single best answer questions usually include five options, out of which the responder has to choose the best answer.
Radiation is a type of heat transfer wherein there is no need for medium or media through which the heat will flow. Consequently, the radiation waves are able to travel through vacuum. The best observation as evidence to conclude that heat is indeed transferred by radiation is the increase of temperature of the receiving body.
Answer:
A.) Pa - Pb
Explanation:
Given that:
A and B are common species of flower ;
Proportion of blue flowers are Pa and Pb for the two species respectively ;
Sample Proportion of blue flower;
Species A = P'a
Species B = P'b
Mean of sampling distribution P'a - P'b
Since the samples are independent and drawn at random, the mean of sampling distribution equals Pa - Pb
