QUESTION 1 Provide an appropriate response. Compute the standardized test statistic, X 2 , to test the claim σ 2 ≥ 12.6 if n = 1

Anna [14]

Answer: 11.667

Step-by-step explanation:

The formula to find the test statistic for chi-square test is given by :-

$\chi^2=\dfrac{(n-1)\cdot s^2}{\sigma^2}$

Given : Claim : $\sigma^2=12.6$

$n = 15\ ;\ s^2 = 10.5$

Then , the standardized test statistic will be :-

$\chi^2=\dfrac{(15-1)\cdot 10.5}{12.6}\\\\=\dfrac{14\cdot 10.5}{12.6}=11.6666666667\approx11.667$

Hence, the standardized test statistic $\chi^2=11.667$

Which graph shows the following:

svetlana [45]

Answer:

The first one, the one with A' at -4,5

Step-by-step explanation:

To find which graph shows the translation you first find a point that is easy to follow, ideally one that is along an axis.

Point A would be easy to follow, since it's roughly at (0,3) initially.

Then we apply the translation. T (-4,2) means the X value is moved to the left, subtracted 4 units... while the Y value is moved up, adding 2 units.

So, the point A that was at (0,3) becomes A' at (0 - 4, 3 + 2), or (-4,5).
