Answer 1

The statistical software output for this problem is:

One sample proportion summary confidence interval: p Proportion of successes Method: Standard-Wald 99% confidence interval results: Proportion Count Total Sample Prop. Std. Err U. Limit L. Limit 15 50 0.3 0.064807407 0.13306718 0.46693282

Hence,

99% confidence interval will be:

0.1331 $\leq \pi \leq$ 0.4669
