snow_lady [41]

Answer: 46

Step-by-step explanation:

Given : Margin of error : E= 17

Standard deviation : $\sigma=70$

Critical value for 90% confidence level : $z_{\alpha/2}=1.645$

Formula to find sample size is given by :-

$n=(\dfrac{z_{\alpha/2}\times \sigma}{E})^2$

i.e. $n=(\dfrac{(1.645)\times 70}{17})^2$

$\Rightarrow\ n=45.880700692\approx46$

Hence, the required minimum sample size = 46.
