In a two-tailed 2-sample z-test you find a P-Value of 0.0278. At what level of significance would you choose to reject the null
Basile [38]

Answer:

5% or 0.05

Step-by-step explanation:

The null hypothesis will be rejected if p-value is less than significance level.

The null hypothesis can be rejected on 5% and 10% level of significance, but 5% level of significance is a suitable choice because when the 5% significance level is used the confidence level is 95% where as in case of 10% the confidence level is 90%. In short, the significance level indicates the probability of rejection of null hypothesis when the null hypothesis is true and the lesser probability of taking that risk will be better.

So, the scenario indicates the suitable significance level as 0.05.

Math question please help <br> If you get this right I will mark you as a brainliest
iogann1982 [59]

Much as you would like it to be D, it isn't. D has its center at (3,4). You must change the sign on both numbers inside the brackets.

You need something that looks like (x + 3)^2 + (y + 4)^2. So it could be A or B. How do you know which? The graph should give you an answer, then we'll talk about it. The red circle is A the blue circle is B. Which one is correct?

The answer to that is that the center is 5 units away from the origin. The radius of this circle is the sqrt(25) = 5 units away from the center. The blue one has a radius of sqrt(5) which is something over 2. It is not enough. So what's the answer?
