Answer:
The p-value is;
d. 0.00131
Step-by-step explanation:
The given question parameters are;
Company A Company B
Sample size 80 60
Sample mean $16.75 $16.25
Population standard deviation σ₁ $1.00 σ₂ $0.95
Therefor, we have;
The p-value = 1 - 0.99869 (the area to the right of 3.01) = 0.00131
x = 11
y = 3
4y+1=6y-5
-4y -4y
+1 =2y-5
+5 +5
6/2=2y/2
3=y
2x-4= 18
+4 +4
2x/2 = 22/2
x=11
w x 3/4 = 35.7
Multiply both sides by 4
then, divide both sides by 3.
That is the answer. I assume you can take it from here.
y=4x+9
