The number that believe there was a conspiracy is k = 614
Generally the sample proportion is mathematically represented as

=> 
From the question we are told the confidence level is 95% , hence the level of significance is
=>
Generally from the normal distribution table the critical value of
is
Generally the margin of error is mathematically represented as
=>
=>
Generally 95% confidence interval is mathematically represented as
=>
=>
.3 = 3/10
.5 = 1/2
.05 = 1/20
.25 = 1/4
