Respuesta :

The p-value of the given sample statistic is; 0.0314

How to find the p-value?

We are given;

Sample size; n = 514

Number of success; x = 236

p = 0.5

p^ = 236/514 = 0.459

The formula for z-score is;

z = (p^ - p)/(p(1 - p)/n)

z = (0.459 - 0.5)/√(0.5(1 - 0.5)/514)

z = -1.86

From online p-value from z-score calculator using α = 0.01, we have;

p-value = 0.0314
