The null and alternative hypotheses for a hypothesis test of the difference in two population proportions are: Null Hypothesis:
Alternative Hypothesis:
Notice that the alternative hypothesis is a one-tailed test. Suppose proportions z-test method from statsmodels is used to perform the test and the output is (1.13, 0.263). What is the P-value for this hypothesis test?
a. -1.13.
b. 1.13.
c. 0.263.
d. 0.1315.

step-by-step explanation:

∆abc has the points a(1, 7), b(-2, 2), and c(4, 2) as its vertices. formed with the point d(1, 2) as its third vertex, then ∆abd is triangle.

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2

answer:

24pi or letter c
