sample proportion, = 0.4802
sample size, n = 1058
Standard error, SE = sqrt(pcap * (1 - pcap)/n)
SE = sqrt(0.4802 * (1 - 0.4802)/1058) = 0.0154
Given CI level is 99%, hence α = 1 - 0.99 = 0.01
α/2 = 0.01/2 = 0.005, Zc = Z(α/2) = 2.58
Margin of Error, ME = zc * SE
ME = 2.58 * 0.0154
ME = 0.0397

SE = sqrt(p*(1-p)/n)
SE = sqrt(0.5*(1-0.5)/1058)
std.error = 0.0154

Test statistic,
z = (pcap - p)/sqrt(p*(1-p)/n)
z = (0.4802 - 0.5)/sqrt(0.5*(1-0.5)/1058)
z = -1.2881
