Claire knows the z score for her research hypothesis is –2.05, and her critical values are –1.96 and 1.96 for a p value of 0.05.

What should she conclude about her hypothesis given these statistics?

Answer:

Step-by-step explanation:

Hello!

The critical values are the values of the distribution that mark the bonds of the "rejection region" and the "not rejection region".

Under the Z distribution with α: 0.05, if the critical values are -1.96 and 1.96 this means that:

-1.96 < Z < 1.96 is the "region of support" of the null hypothesis and any other value of Z, either below or equal to -1.96 or above or equal to 1.96 will determine the rejection of the null hypothesis.

In this case, the obtained Z value is -2.05, this value is less than -1.96, meaning it is within the "rejection region" so Claire should reject the null hypothesis.

I hope it helps!

Find the value of x.
Colt1911 [192]

Answer:

  x = 16 2/3

Step-by-step explanation:

The altitude divides the triangle into similar triangles. We can form the ratio between the hypotenuse and the short leg for two of the triangles. Those ratios will be a proportion:

  10/6 = ((x-6) +6)/10

  100/6 = x . . . . . multiply by 10 and simplify

  x = 16 2/3

The graph shows g(x), which is a translation of f(x)=|x|. Write the function rule for g(x).
Kay [80]

Answer:

  g(x) = |x| -9

Step-by-step explanation:

In the form ...

  g(x) = a|x -h| +k

the parameters are ...

  • a: the vertical scale factor (1)
  • h: the right shift of the vertex (0)
  • k: the upward shift of the vertex (-9)

The vertex of |x| is (0, 0). The vertex of g(x) is (0, -9), so there has been a vertical shift of -9 and no horizontal shift. The slopes of the lines on the graph of g(x) have a magnitude of 1, so the vertical scale is not changed from the original function (a=1).

Then the translated function is ...

  g(x) = |x| -9
