l. with the US Ammy to build a fumace to decontaminate Vx projectiles through thermal decomposition. The data below represents thermal couple (temperature) measurements (in C) for three projectiles at locations on the The the right is an Anova analysis on this set of data. Answer the questions below. Note to answer the questions correctly you will need to know when and how to apply the appropriate procedures from Chapters 8 and 10.

Solution

c.

Note that              
Margin of Error E = t(alpha/2) * s / sqrt(n)              
Lower Bound = X - t(alpha/2) * s / sqrt(n)              
Upper Bound = X + t(alpha/2) * s / sqrt(n)              
              
where              
alpha/2 = (1 - confidence level)/2 =    0.05          
X = sample mean =    1041.7          
t(alpha/2) = critical t for the confidence interval =    2.015048373          
s = sample standard deviation =    79.6          
n = sample size =    6          
df = n - 1 =    5          
Thus,              
Margin of Error E =    65.48214827          
Lower bound =    976.2178517          
Upper bound =    1107.182148          
              
Thus, the confidence interval is              
              
(   976.2178517   ,   1107.182148   ) [ANSWER]
