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:

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