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
Answer:
they are congruent
Step-by-step explanation:
the green triangle is just being cut in half such as the left side it is 2 while the blue one is 4
Hello there!
1/8 ÷ 3/4
= 1/8 * 4/3
= 1/24/4
=1/96
= 0.01
I hope this helps!
Priscilla's weighted average grade in her Calculus course is 77.5%.
<h3>Calculating weighted average</h3>
In order to determine the weighted average, you will multiply each contributor by its individual weight and then take the sum as shown:
Weighted average = 0.50(87%) +0.30(100%) +0.20(20%)
Weighted average = 43.5% +30% +4%
Weighted average = 77.5%
Therefore Priscilla's weighted average grade in her Calculus course is 77.5%.
