Answer:

The answer is "0.45 \pm 0.18204"

Step-by-step explanation:

For the +4 sample proportion= \frac{(7+2)}{(16+4)} =  \frac{9}{20} = 0.45

Sample percentage measurements estimated stdev

= \sqrt{\frac{[(0.45)(1-0.45)]}{[(16+4)]}}\\\\ = \sqrt{\frac{[(0.45)(0.55)]}{[(20)]}}\\\\ = \sqrt{\frac{0.2475}{20}}\\\\= \sqrt{0.012375}\\\\=0.111

Calculating the critical z for a=0.1, two-tailed = 1.64

Calculating the confidence interval:

= 0.45 \pm 0.111 \times 1.64 \\\\= 0.45 \pm 0.18204
