A medical researcher compares a new treatment for poison ivy against a traditional ointment. He finds that the new treatment significantly reduces itching, with a p-value of 0.047. What does the p-value mean in this context?

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:

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.

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
