Sagot :

Answer: 0.03

Explanation:

The standard error will be calculated as:

= ✓p(1-p) / ✓n

where,

p = 57/186 = 0.3065

n = 186

We then slot the values back into the formula and this will be:

= ✓p(1-p) / ✓n

= ✓0.3065(1 - 0.3065) / ✓186

= ✓(0.3065 × 0.6935) / ✓186

= ✓0.2124884 / ✓186

= 0.03
