Given that, n = 1015 and x = 590
a) Point estimate of the population proportion is,
=> Point estimate = 0.581
b) A 95% confidence level has significance level of 0.05 and critical value is, Zcrit = 1.96
The margin of error (E) is,
=> E = 0.030
c) The 95% confidence interval for the population proportion is,
Answer : 0.551 < p < 0.611
