Step-by-step explanation:
Answer:
H0: p1-p2=0
Ha: p1-p2≠0
This hypotheses can be written as
H0: p1=p2
Ha: p1 ≠p2
Step-by-step explanation:
Here the claim is if these data provide strong evidence the rate of sleep deprivation is different for the two states which will be formulated as alternate hypothesis .
Ha: p1-p2≠0
The null hypothesis is
H0: p1-p2=0 i.e these data do not provide strong evidence the rate of sleep deprivation is different for the two states.
where p1 = as population 1 of California
p2= as population 2 of Oregon
This hypotheses can be written as
H0: p1=p2
Ha: p1 ≠p2
which will also give the same results as above and a two tailed test will be performed for both hypotheses.

Answer:
6 * 42 = 6 * (20 + 22)
= (6 * 20) + (6 * 22) = 120 + 132 = 252
Step-by-step explanation:
Here, we want to multiply 6 by 42 using distributive property
In this case, we can have the distributive property as;
a * ( b + c) = ab + bc
Thus, we can represent 42 as (20 + 22)
so 6 * 42 becomes 6 * (20 + 22)
Using the distributive property, we have
(6 * 20) + (6 * 22)
= 120 + 132 = 252
To factor x^2 + 2x - 8 follow these steps
1) Write to factors, with x as the first term, this way:
(x )(x )
2) The sign to the right of the x in the first factor is the same sign of the coeficient of x in the polynomial.
That is +.
The sign to the right of the x of the second factor is the product of the sign of the coefficent of x (this is +) and the sign of the independent term (this is - ).
So that is (+).(-) + -.
Now the two factors have this form:
(x + ) (x - )
3) Now find two numbers whose product is - 8 and whose difference is +2
Those numbers are + 4 and -2.
Then the two factors are:
(x + 4) (x - 2).
So the answer if that the correct factorization is (x + 4) (x - 2)
