A, B, and C are all equal to the ratio 7:5
If you simplify each of the numbers in A, B, and C, you will find that they will come to equal 7:5
Answer:
a) critical values ≈ -3.182 and 3.182 shows that there is difference in average prices
b) H0 : μd = 0
Ha : μd ≠ 0
Step-by-step explanation:
<u>a) Determine if there is any significant difference in the average prices </u>
using ∝ = 0.05
and μ( advertiser ) - μ ( competitor ) = μd
test statistic ( t ) = -3.011
df = 3
hence the critical values ( two tailed test ) = -3.182 and 3.182. this shows that there is sufficient evidence to show that there is difference in the average prices
<u>b) state the hypothesis</u>
H0 : μd = 0 ( null )
Alternate hypothesis : Ha : μd ≠ 0
Many fractions are equal. You can double both numbers to make a new fraction with the same properties, or times them both by 10 or more.

Hello there!
To find this, we must simplify this equation.
first, let's simplify the right side
-1 * x = -x
-1 * 5 = -5
Now, we have: y -3 = -x -5
Now we must add + 3 to each side to get rif of the negative three
now we have y = -x - 2
So, your answer is B.) y= -1x - 2
I hope my answer was of assistance!
