Answer:

Step-by-step explanation:

Hello!

To decide over a hypothesis test using a confidence interval the following conditions are to be met:

1. The hypotheses should be two-tailed.

2. The hypotheses and the confidence interval should be made for the same parameter.

3. The confidence level and the significance level should be complementary, so if the CI is 1-α: 0.99 the level of significance should be α: 0.01

If all conditions are met, the decision rule is the following:

If the value stated in the null hypothesis is contained by the CI, the decision is to not reject the null hypothesis.

If the value stated in the null hypothesis is not contained by the CI, the decision is to reject the null hypothesis.

Let's say in this example the hypotheses are:

H₀: μ = 71

H₁: μ ≠ 71

α: 0.01

99% Confidence level is (71.36;78.64).

As you can see, 71 is not contained in the CI so the decision to take is to reject the null hypothesis, in other words, the population mean is not 71.

I hope it helps!

Emelina wrote the equation of a line in point-slope form as shown below.
Harman [31]

Answer: y=3x+2

Step-by-step explanation:

Given: Emelina wrote the equation of a line in point-slope form as shown below.

(y+4)=3(x+2)

To write the equation in intercept form, first we multiply 3 inside the bracket values in the right side , we get

y+4=3x+6

Now, subtract 4 from both sides , we get

y=3x+2

Hence, Emelina’s equation in slope-intercept form : y=3x+2
