Answer:13,15A 14D
Step-by-step explanation:
Replace y with 0 and solve for x.
x= -1.52138
it is -3.
The pattern is that each number is divided by two
-48/2=-24
-24/2=-12
-12/2=-6
-6/2=-3
And so on...
Answer:
C with 3000 successes of 5000 cases
Step-by-step explanation:
In test statistics the number of samples goes a long way in determining the result of a test.
Using the z score formula
Test statistic z score can be calculated with the formula below;
z = (p^−po)/√{po(1−po)/n}
Where,
z= Test statistics
n = Sample size
po = Null hypothesized value
p^ = Observed proportion
Therefore the z score is directly proportional to the square root of the sample size.
z ∝ √n
The higher the sample size, the higher the z score, the higher the evidence of confirming the alternative hypothesis.
Since the all have the same proportion (0.6), and options c has the highest sample size (5000 cases), it will give the strongest evidence for the alternative hypothesis
Loan B has the lower interest rate 12%.
