Explanation & Answer
given,
for western residients
population=1360
probability(p1)=0.4
proportion(P1)=544
for southern residients
population=1300
probability(p2)=0.49
proportion=637
difference in proportion=637-544=93
net P= (n1*p1-n2*p2)/(n1+n2)=0.0349
N,difference in population=60
total population=2660
Z at 90%=1.645
S.D=0.019
upper limit=(p1-p2)+Z*S.D/(n)^0.5=(0.4-0.49)+1.645*0.019/(60)^0.5=0.09+0.00403=0.09403
lower limit=(p1-p2)-Z*S.D/(n)^0.5=0.09-0.00403=0.08547

answer two questions about sample and survey
Please answer the 2 essay questions below and each questions needs about 350-500 words.You are tasked with developing a sample of 100 employees from a population of 400 employees. Approximately 60% of the employees are women and 40% of the women are racial/ethnic minorities. Approximately 33% of the male employees are racial/ethnic minorities. Discuss how you might develop a stratified fandom sample and tell me how many racial/ethnic minority females and how many racial/ethnic minority males will eventually be in your sample.Provide a detailed discussion of the advantages and disadvantages associated with using closed and open-ended questions in conducting surveys involving human research subjects.

However, recent studies have shown that earlier monitoring of risk factors such as blood pressure can be very beneficial (The Wall Street Journal, January 10, 2012). Having higher than normal blood pressure, a condition known as hypertension, is a major risk factor for heart disease. Suppose a large sample of individuals of various ages and gender was selected and that each individual’s blood pressure was measured to determine if they have hypertension. For the sample data, the following table shows the percentage of individuals with hypertension.a.Develop a side-by-side bar chart with age on the horizontal axis, the percentage of individuals with hypertension on the vertical axis, and side-by-side bars based on gender.b.What does the display you developed in part (a), indicate about hypertension and age?c.Comment on differences in gender.AgeMaleFemale20 - 3411.0%9.0%35 – 4424.0%19.0%45 – 5439.0%37.0%55 – 6457.0%56.0%65 – 7462.0%64.0%75 +73.3%79.0%3.The department of transportation’s study on driving speed and miles per gallon for midsize automobiles resulted in the data below.a.Plot the speed and miles per gallon using a scatter plot with speed on the horizontal axis.b.Compute the sample mean and standard deviation for each variable.c.Compute the sample correlation coefficient.

The following cross-tabulation shows the number of households (1,000s) and the household income by the highest of level of education for the head of the household (U.S. Census Bureau website, 2013).
