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
