THIS IS THE DATA SO HELP ME!! PLEASE!
1. Use an appropriate sampling technique to find a sample of 15 African nations and a sample of 10 European nations. Describe your technique and list the nations.
2. Use your samples to test the claim that Africa experiences a higher mean maternal mortality rate than Europe

1. The sample of 15 African nations and the sample of 10 European nations have been given. A suitable techniques is to sample the 15 African nations and 10 European nations is to list them first separately. Then use the random number generator or random digit table to select the African nations and European nations separately.
2. In order to test the claim, follow the steps of hypothesis testing.
State the hypotheses: The null hypothesis is the hypothesis of no difference. Therefore, it states that there is no difference in population mean mortality rat eof Africa and Europe. It is of interest to know whether Africa experiences a higher mean mortality rate than Europe. Therefore, the hypotheses are as follows:
H0:muA-muE=0
H1:muA-muE>0
Assumptions: The samples are drawn randomly, mortality rate of one nation is independent of other, the histogram of mortality rate of both Africa and Europe is roughly normal. Thus, use t-distribution to draw inference about two population means.
Test statistic:
Using technology, xbar A=409, sA=295, nA=15
xbar E=8.50, sE=4.25, nE=10, where, xbar is sample mean, s is sample standard deviation, n is sample size.
t=(xbarA-xbarE)/sqrt[s^2A/nA+s^2B/nB]
=(409-8.50)/sqrt[295^2/15+4.25^2/10]
=5.26
The p value at 14 degrees of freedom is 0.000.
[Note: df=[(s1^2/n1+s2^2/n2)/{1/n1-1(s1^2/n1)^2+1/n2-1(s2^2/n2)^2]]
Rejection rule: Per rejection rule based on p value, reject null hypothesis if p value is less than alpha=0.05. Here, p value is less than 0.05, therefore, reject null hypothesis.
Conclusion: There is suffiicnet sample evidence to conclude that Africa experiences a higher mean maternal mortality rate than Europe.
