Answer: 554
Step-by-step explanation:
If prior population proportion is known, then the formula to find the sample size is given by :-

As per given description, we have
p= 0.1
E=0.025
Critical z-value for 95% confidence : 
Then,

Hence, the minimum sample size required = 554.
Answer: using A= bh/2 THe height is 9.23
Step-by-step explanation: First, with the Right Angle at the bottom, usr the sides to compute the area: 12*5=60
THen Imagine the side=13 as the base, so you have b=13 for the formula
use the formula A= bh/2
60 = 13h/2 ==> 2(60) =13h --> 120/13 = h
h = 9.23
