Answer:

Step-by-step explanation:
6-4[x+1-(y+3)]+6y
6-4[x+1-y-3]+6y
6-4[x-2-y]+6y
6-4x+8+4y+6y
14-4x+10y
Answer:
The answer is "between 0.10 and 0.05".
Step-by-step explanation:
For sample 1:

For sample 2:
Calculating the null and alternative hypotheses:
Calculating the test statistic:

Calculating the conservative degrees of freedom:
by using Excel the p-value for left tailed test and for test statistic will be
with
.

4y=3x-24
y=3/4x-6
the line intersect x axis in A
y=0, 3/4x=6, 3x=24, x=8 ⇒ A (8,0)
the line intersect y axis in B
x=0, y=-6 ⇒ B (0,- 6)
a.the gradient of l is 3/4
b. AB= V 6^2 +8^2=V36+64=V100=10
