Answer:
I'm wonde what it is because I like this stuff
Answer:
H0: σ1=σ2
Ha : σ1 >σ2
B. Upper H 0H0:
sigma Subscript 1 Superscript 2σ21equals=sigma Subscript 2 Superscript 2σ22
Upper H 1H1:
sigma Subscript 1 Superscript 2σ21greater than>sigma Subscript 2 Superscript 2σ22
Step-by-step explanation:
The claim is that the treatment group has errors that <em><u>vary significantly</u></em> more than the errors of the placebo group.
The claim is the alternative hypothesis and the opposite of claim is the null hypothesis.
Vary significantly means that it is greater than so we choose the alternate hypothesis of greater than and the null hypothesis will be equal to errors of the placebo group.
So the correct choice is B.
B. Upper H 0H0:
sigma Subscript 1 Superscript 2σ21equals=sigma Subscript 2 Superscript 2σ22
Upper H 1H1:
sigma Subscript 1 Superscript 2σ21greater than>sigma Subscript 2 Superscript 2σ22
Choice A,C and D all are incorrect.
This can be written as
H0: σ1=σ2
Ha : σ1 >σ2
So I will be assuming that EG = 8 is the length
of the line segment EG. If that's the case, therefore the coordinates of G would
simple be:
G =11 ± 8
G = 11 – 8, 11 + 8
G = 3, 19
<span>So G can have a coordinate of 3 or 19.</span>
Answer:
1010 base 9 Changing from base to decimal we start from left side digit and multiply by base
1000 * 9^3 = 729
1 * 9 = 9
We sum and get 738
85 base 9 =
8 * 9 = 72
5 = 5
We sum 72 + 5 = 77 decimal
738 - 77 = 661 decimal
and if the answer must be in base 9 then:
661 decimal = 814 base 9
Step-by-step explanation:
Triangle is missing, so i have attached it.
Answer:
Radius = 10.82
Step-by-step explanation:
From the image attached, the triangle is obviously a right angle triangle and therefore, the missing side (AB) which is the radius can be found via pythagoras theorem.
We are given;
AC = 21
BC = 18
Thus;
|AC|² = |AB|² + |BC|²
21² = |AB|² + 18²
|AB|² = 441 - 324
AB = √117
AB = 10.82
