l with the US Ammy to build a fumace to decontaminate Vx pro
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]
