Answer:
a.
b-Check illustration below
c.(-0.0517,0.0177
Step-by-step explanation:
a.let denote processes 1 & 2.
For : T1=10,n1=200
For :T2=20,n2=300
Therefore
b. To test for hypothesis:-
i.
ii.For a two sample Proportion test
iii. for (0.5 alpha IS 0.025),
reject if
iv. Do not reject . The noncomforting proportions are not significantly different as calculated below:
z=-0.78
c. for the p1-p2 is given as:
=(-0.0517,+0.0177)
*CI contains o, which implies that proportions are NOT significantly different.
The right answer is C
Let me to explain. From the graph we know that the vertex of this parabola is . This is a<em> maximum y-value.</em> We also know that the parabola <em>opens downward, </em>so the leading coefficient is negative. Given that the function is even and the leading coefficient is negative, it follows that the graph falls to the left and right. In a mathematical language this is:
