Answer:
0.047 is the probability that new treatment significantly reduces itching provided the null hypothesis is true.
Step-by-step explanation:
We are given the following in the question:
Hypothesis:
New treatment for poison ivy against a traditional ointment.
P-value = 0.047
P-value:
- The p-value is the probability of obtaining observed results of a test, provided that the null hypothesis is true.
- It is the level of marginal significance for the probability of the happening of a given event.
Interpretation:
Thus, 0.047 is the probability that new treatment significantly reduces itching provided the null hypothesis is true that is the new treatment and the traditional ointment have the same effect.
Answer:
y = 3
Step-by-step explanation:
3(2y-3) = -4y+21
6y-9 = -4y+21
10y-9 = 21
10y = 30
10y/10 = 30/10
y = 3
