Answer:
A. D
B. χ2 > 3.841
C. χ2 = 3.4806
D. 0.0621
Step-by-step explanation:
Question A: The hypotheses the dean should use are:
a) H0 : π1 - π2 ≥ 0 versus H1 : π1 - π2 < 0.
b) H0 : π1 - π2 ≤ 0 versus H1 : π1 - π2 > 0.
c) H0 : π1 - π2 ≠ 0 versus H1 : π1 - π2 = 0.
d) H0 : π1 - π2 = 0 versus H1 : π1 - π2 ≠ 0.
Answer: (d)
H0 : π1 - π2 = 0 versus H1 : π1 - π2 ≠ 0.
(B). Referring to the scenario above, the null hypothesis will be rejected if the test statistic is ________.
Answer: χ2 > 3.841
(C). Referring to the scenario above, the value of the test statistic is ________.
Answer: χ2 = 3.4806 (using the formula)
(D). Referring to the scenario above, the p-value of the test is ________.
Answer: 0.0621 (the answer could be looked up, in table)

Step-by-step explanation:
E.
Because
30+20=50
and
30-20 = 10
The answer is the bottom one with 8/ (x^4 p^9 y^8)
Thanks for the fun question !! :D
Hello!
8y - 1 = x
3x = 2y
Put what x equals in the first equation in place of x in the second equatoin
3(8y - 1) = 2y
Distribute the 3
24y - 3 = 2y
Subtract 24y from both sides
-3 = -22y
Divide both sides by -22
y = 3/22
Now we put y into the first equation
8(3/22) - 1 = x
Multiply
12/11 - 1 = x
Subtract
1/11 = x
The answer is (1/11, 3/22)
Hope this helps!
