Answer: 271
Step-by-step explanation:
As per given description in the question, we have
Critical value for 90% confidence interval =
[using z-value calculator ]
Margin of error : E= 0.05
Since prior estimate of population proportion is unknown so we take p= 0.5
Formula we use to find the sample size :
[we assume p= 0.50]
i.e. 
Simplify :
Therefore , the minimum sample size required = 271

Answer:
Step-by-step explanation:
1 - V = (l(w)h)/3 = (14·9.5·15)/3 = 665ft^3
2 - 73.5ft^3 C
3 - (8·8·12)/3=256in^3
4 - (1.5·2·4)/3 = 4cm^3
5 - (12·6·9)/3=216in^3
The radius would be 5. Hope this was helpful! thank you for your time!
