For the samples taken from two populations, the difference between the sample means does not fall within the 95% confidence interval. if the null hypothesis is, “there is no difference in the sample means,” which statement is true?

a.
the null hypothesis must be accepted.
b.
the null hypothesis must be rejected.
c.
both the null and the alternative hypotheses must be rejected.
d.
both the null and the alternative hypotheses must be accepted.

Option B is right

Step-by-step explanation:

Given that there was a comparison test for two samples done. The differnce between the sample means does not fall within 95% confidence interval.

This means that there is 95% chance that there will be a significant difference between the two means.

Hence whenever we compare two samples, we find the mean difference, margin of error, and confidence interval 95%

Whenever the mean difference does not fall within the confidence interval, we find that the null hypothesis namely that the two means are equal cannot be accepted

Hence option B is true.

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

1 1/7 hope i

step-by-step explanation:

8/7 = (1 * 7 + 1) / 7 = 1 + 1/7 = 1 1/7
