Answer:

All real numbers

Step-by-step explanation:

The domain of the function is the set of real values that can be substituted into a function to produce a valid output. Any real number can be substituted into the function (y = x), and produce a valid output. Thus, the domain is all real numbers.

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 $\chi^2=11.667$

b) 2

c) 2

d) 2

Median:

a) 4,2

b) 5,2

c) 5,1

d) 4,1

Mode:

a) 1

b) 1

c) 1

d) 1

Step-by-step explanation:

Mean:

a) 1+4+2+1 = 8/4=4

b)1+5+2+1 = 9/4= 2.25 (round to the nearest whole number = 2)

c) 1+5+1+0 = 7/4 = 1.75 (round to the nearest whole number = 2)

d) 1+4+1+0 = 6/4 = 1.5 (round to the nearest whole number = 2)
