Anettt [7]

Answer: 554

Step-by-step explanation:

If prior population proportion is known, then the formula to find the sample size is given by :-

n=p(1-p)(\dfrac{z_{\alpha/2}}{E})^2

As per given description, we have

p= 0.1

E=0.025

Critical z-value for 95% confidence : z_{\alpha/2}=1.96

Then,

n=0.1(1-0.1)(\dfrac{1.96}{0.025})^2=553.1904\approx554

Hence, the minimum sample size required = 554.

8y - 5 = 99 \\  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \: 8y = 99 + 5 \\ \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  8y = 104  \\ \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:   y=  \frac{104}{8}   \\ \:  \:  \:  \ \:  \:  \:  y = 13

\:  \:  \:  \:  \:  \: 2y + x = 38.4 \\ 2(13) + x = 38.4 \\  \:  \:  \:  \:  \:  \: 26 + x = 38.4 \\ \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:   x = 38.4 - 26 \\ \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  x = 12.4
