1 pound is more than 15 ounces
Answer: 271
Step-by-step explanation:
The formula we use to find the sample size is given by :-
, where is the two-tailed z-value for significance level of
p = prior estimation of the proportion
E = Margin of error.
If prior estimation of the proportion is unknown, then we take p= 0.5 , the formula becomes
Given : Margin of error : E= 0.05
Confidence level = 90%
Significance level
Using z-value table , Two-tailed z-value for significance level of
Then, the required sample size would be :
Simplify,
Hence, the required minimum sample size =271
