C because u have 3/7 which is a fraction
Answer:
2nd option
Step-by-step explanation:
Repeatedly divide by 2 until the value 1 is reached
32 ÷ 2 = 16
16 ÷ 2 = 8
8 ÷ 2 = 4
4 ÷ 2 = 2
2 ÷ 2 = 1 ← finish here
Then
32 = 2 × 2 × 2 × 2 × 2
I think that the answer is m = -1
make a line going straight from (0,0) to (2,2) and so on and the other line starts at (0,0) and go to (1,1) and follow along the other line
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
