An advocacy organization surveys 1203 citizens of country A and 233 of them reported being born in another country. Similarly, 164 out of 1151 citizens of country B reported being foreign-born. The researchers want to test if the proportions of foreign-born are the same in country B as in country A. Complete parts a through c below.
a. What is the difference in the sample proportions, p1- p2 of foreign-born residents from both countries? Assume p1 is the proportion of foreign-born residents from country A and p2 is the proportion of foreign-born residents from country B.
b. What is the value of the z-statistic?
c. Write the appropriate hypotheses
d. What do you conclude at a=0.01
Find P-value
State conclusion

Researchers from a certain country were interested in how characteristics of the spleen of residents in their tropical environment compare to those found elsewhere in the world. The researchers randomly sampled 93 males and 107 females in their country. The mean and standard deviation of the spleen lengths for the males were 112 cm and 0.9 cm, respectively, and those for the females were 10.3 cm and 0.7 cm, respectively. At the 5% significance level do the data provide sufficient...
