Answer:
Null and alternative hypotheses:
H0: p1 = p2
H1: p1 ≠ p2
To find the sample proportions, we have the following:
Calculate Z statistics:
Z = -2.764
P-value = 0.00285
The pvalue is low.
Since the pvalue is low, reject null hypothesis, H0.
Conclusion:
There is strong evidence that patients experiencing the primary outcome is different for those receiving the treatment compared to those without
Answer:
The correct answer is 7 : 8.
Step-by-step explanation:
There are 14 girls and 2 boys taking karate lessons.
Total number of students taking the karate class is 16.
The ratio that compares the number of girls taking karate lessons to the total number of students taking karate lessons is given by 14 : 16 = 7 : 8.
This can be interpreted as for every 8 students in the karate lesson, 7 of them are girls.
If we want to calculate the time it takes to fill a water tank, we need the flow and volume of the tank.
The flow must be a data, but for the volume of the tank we need mathematics.
For example, if it is a cylinder, we need mathematics to know that the volume of the cylinder is:
V = pi * r ^ 2 * h
