Answer:
The 99% confidence interval is
Step-by-step explanation:
From the question we are told that
The sample size is n = 100
The sample mean is
The population standard deviation is
From the question we are told the confidence level is 99% , hence the level of significance is
=>
Generally from the normal distribution table the critical value of is
Generally the margin of error is mathematically represented as
=>
Generally 95% confidence interval is mathematically represented as
=>
=>
To answer this question, you will use the formula given to find the volume of concrete.
V = 3.14 x 0.6^2 x 30
V = 33.912m³
The volume of concrete is approximately 33.912 m³.
6.4*10=64
6.4*2=12.8*10*1/2=64
