Answer:
Accept the null hypothesis if it is two tailed test.
Step-by-step explanation:
The null hypotheses can only be accepted if it is a two tailed test and calculated chi square must be less than the critical value of chi square.
Then the difference between the the observed and expected frequencies will be zero.
where
H0 : σ²-σ²= 0 Ha: σ²-σ²≠0
For this the critical region would be greater than the calculated value of chi square. If so we will accept the null hypothesis and reject the alternative hypothesis.

Step-by-step explanation:
the rule is x+1 y+2 for each of the vertices
Answer:
point a are (-10,-4) and point I are (-3.875,-10.125)
Step-by-step explanation:
C=πd ⇒ d = C/π = 28.27/3.14 ≈ 9 <span>inches</span>
4x+19=7x+16
4x=7x-3
-3x=3
x=1
