Answer 1

a)
pcap = 527/1013 = 0.5202

c)
for 95% CI, z-value = 1.96

ME = 1.96*sqrt(0.5202*(1-0.5202)/1013))
= 0.0308

CI = (0.5202 - /+ 0.0308)
= (0.4894, 0.5510)

option B

d)
No supermajority do not think it is a luxury because the CI lies below 0.6

e)
CI = (1- 0.5510, 1- 0.4894)
= (0.449 , 0.5106 )
