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

yes

Option C: -0.5 is the right answer
Step-by-step explanation:
Given is the graph on which different points are indicated.
We have to find the y-coordinae of the mid-point of WU.
The formula for mid-point is:
So we only have to know the y-coordinates of both points to find the mid-points y coordinate
So by observing the graph we get
y_1 =0
y_2 = -1
So,
Hence,
Option C: -0.5 is the right answer

Step-by-step explanation:
Answer:
.13 cents per can
Step-by-step explanation:
If you bought 18 cans with $2.30, you need to divide 2.30 by 18 becauseyou need to find out the unit price for each can. When you divide .2.30 by 18 you get .1277777repeaing so you can just round up from there and get .13 cents.
