The answer to the question above is "brand names cause consumers to be more sensitive to product differences" based on the result of Roberto's taste test.

Since Clay looked through ten different propositions and found them to all be ineffective, the reason attributed to this will be due to the fact that the propositions were generic, and had no unique value communicated.
Tough.. Just write a little stick figure guy saying I dunno. :) Hope I helped!
a) ( 0.8509718, 0.8890282)
b) ( 0.7255, 0.7745)
Explanation:
(a)
Given that , a = 0.05, Z(0.025) =1.96 (from standard normal table)
So Margin of error = Z × sqrt(p × (1-p)/n) = 1.96 × sqrt(0.87 × (1-0.87) / 1200)
=0.01902816
So 95 % confidence interval is
p+/-E
0.87+/-0.01902816
( 0.8509718, 0.8890282)
(b)
Margin of error = 1.96 × sqrt (0.75 × (1-0.75) / 1200) = 0.0245
So 95% confidence interval is
p+/-E
0.75+/-0.0245
( 0.7255, 0.7745)
