Complete Question
A civil engineer is analyzing the compressive strength of concrete. Compressive strength is normally distributed with
. A random sample of 12 sample specimens has a mean compressive strength of 
. Round your answers to 1 decimal place. (a) Calculate the 95% two-sided confidence interval on the true mean compressive strength of concrete.
Answer:
Step-by-step explanation:
From the question we are told that:
Sample size 
Standard deviation 
Sample mean 
Confidence level =95%
significance level
From table \alpha 0.05
Gives
Generally the equation for confidence interval is mathematically given by
Step-by-step explanation:
- Pick two whole points on the graph
- Then, use this formula: Y2 - Y1
X2 - X1
- Finally, you're given a solution (slope)
The x-coordinate of the right-most point of S' is 4. In the original, it is 6. The dilation multiplier is 4/6 = 2/3.
Selection B matches that.
