The answer is "0.34 \pm 0.060".

Step-by-step explanation:

Point estimate = Sample proportion = \frac{102}{300}= 0.34

For 95\% confidence, z = 1.96

Hence,

Margin of error= 1.96 \times \sqrt{0.34\times \frac{0.84}{300}}=1.96 \times 0.0308 = 0.060

Therefore,

Confidence interval in the tri-equality form:

\to 0.34 - 0.060 < p < 0.34 + 0.060\\\\\to 0.28 < p < 0.4

Confidence interval using point estimate and margin of error:

p = 0.34 \pm 0.060
