How do you find the m and b in the problem y=-x+1?

inysia [295]

In Y=mx+b:

m=slope. That is found by using this formula y2-y1/x2-x1

b=y-intercept. That's found by finding slope, m, and substituting that into y=(m)x+b. Then you have to solve for b and that'll be your y-intercept.

Answer:

The test statistic is t = 3.36.

Step-by-step explanation:

You're testing the claim that the mean difference is greater than 0.7.

At the null hypothesis, we test if the mean difference is of 0.7 or less, that is:

$H_0: \mu \leq 0.7$

At the alternate hypothesis, we test if the mean difference is greater than 0.7, that is:

$H_1: \mu > 0.7$

The test statistic is:

$t = \frac{X - \mu}{\frac{s}{\sqrt{n}}}$

In which X is the sample mean, $\mu$ is the value tested at the null hypothesis, s is the standard deviation of the sample and n is the size of the sample.
