A random sample was selected to determine whether the gas fuel cost different between east side (consider as 1) and west side (consider as 2). Given α=0.05. The data are summarized below:

East Side West Side Difference

Average 2.90/gal 2.99/gal -0.09/gal

Count 12 12 12

Standard deviation 0.81 0.95 0.38

(d) Is there sufficient evidence to indicate that the gas fuel cost different between east side and west side?

Group of answer choices

Yes

To determine whether the pipe welds in a nuclear power plant meet specifications a random sample of welds is selected

To determine whether the pipe welds in a nuclear power plant meet specifications a random sample of welds is selected, and tests conducted on each. Weld strength is measured as the force required to break the weld. Suppose the specifications state that mean strength of welds should exceed 100lb/in2; the inspection team decides to test Ho : μ = 100 versus Ha : μ < 100 why is this not as good as Ha : μ > 100
