Textbook Question
Chapter 5, Problem 5.34P
Estimate the uncertainty at 95% confidence in the strength of a metal alloy. Six separate specimens are tested with a mean of 448.1 MPa and standard deviation of 1.23 MPa in the results. A systematic standard uncertainty of 1.48 MPa with vt, = 19 is estimated by the operator.

An electrical firm manufactures light bulbs that have a lifetime that is approximately normally distributed
with a standard deviation of 36 hours. A lifetime test of n=36 samples resulted in the sample average of
1510 hours. Assume the significance level of 0.05.
(a) Test the hypothesis HO:µ=1500 versus H1:µ#1500using ap-value. (10pts)
(b) Calculate the power of the test if the true mean lifetime is 1510. (10pts)
Pressure distribution measurements are made on a two-dimensional wing model placed in a wind tunnel. The difference between the static pressure sockets on the surface and the static pressure of the free stream is measured. 30 data is taken at each measurement point. The average of the values measured from one of the sockets near the trailing edge was calculated as 2.30 Pa, and the standard deviation was calculated as 2.65 Pa. After applying the Chauvenet criterion to these measurement values, it was decided to eliminate 3 measurements and the new mean value was found to be 2.18 Pa and the standard deviation was 2.42. It was verified that the unexcluded data fit the normal distribution curve. Data above how many Pa and below how many Pa were eliminated? Estimate how many data have negative value (?<0) after elimination.
A small sample (N = 7) of the static coefficient of friction (µ) between two materials is measured with the following data set:
0.0043 0.0050 0.0053 0.0047 0.0031 0.0051 0.0049
Test the data for outliers. Determine the mean value and its confidence.
