12. A pharmaceutical company claims that side effects will be experienced by fewer than 20% of the patients who use medication X

. A clinical trial with a random sample of 400 patients was conducted in which half of the patients were randomly assigned to take medication X and the other half received a placebo. Of those that received medication X they find 68 who experienced side effects.
Assuming all conditions for inference were met, which of the following is a 90 percent confidence interval for the proportion of patients that will experience side effects while taking medication X?

(A) (0.1391, 0.2009)
(B) (0.2744, 0.4057)
(C) (0.2849, 0.3951)

A. Using information in the graph shown, compare the data trend from 1960 to 2015 for sub-Saharan Africa to the trend shown for
expeople1 [14]

Answer:

A. From the information given in the graph, we have;

The grain yield in pounds per acre for Europe in 1960 is approximately 1,600 Pounds per Acre

The grain yield in pounds per acre for Europe in 2015 is approximately 5,100 Pounds per Acre

The rate of change of grain yield in Europe ≈ (5,100 - 1,600)/(2015 - 1960) = 63.\overline{63} Pounds per Acre per year

The grain yield in pounds per acre for Sub-Saharan Africa in 1960 is approximately 800 Pounds per Acre

The grain yield in pounds per for Sub-Saharan Africa 2015 is approximately 1,250 Pounds per Acre

The rate of change in grain yield in Sub-Saharan Africa ≈ (1,250 - 800)/(2015 - 1960) = 8.\overline{18} Pounds per Acre per year

Therefore, the grain yield per acre per year in Europe is increasing approximately 8 times the increase in Sub-Saharan Africa

B. Given that the rate of increase in the pounds of grain per Acre per year in Europe is progressively increasing above the average rate of world rate, the market for the grains produced in Europe will be partly the developing countries, thereby reducing the number of farms found in developing countries

C. In stage 4 demographic transition the population growth is stabilizing and therefore where there is an increase in grain yields, there will be an increase in farming and economic activity and a reduction in population growth

Where there is a decrease in grain yield, there will be an increase in activities to restore supply and therefore, a reduction in population

D. One limitation of the data in describing food security at a regional scale is the information required on the population figures in a given region involved in grain farming
