The manufacturer specified accuracy for an EDM measuring a 1500 m distance is+/- 6mm. A standard deviation of +/- 9 mm is obtained with the instrument from 10 observations of a 1500 meter distance. a. Is the instrument meeting specification at a 5% significance level? b. What about at a 1% level of significance?

An HPLC column received from a manufacturer was specified to
have 4000 plates measured under standard conditions with a test
compound. When the customer repeated the test she found only 1500
plates, despite a symmetrical Gaussian peak shape. What might
account for this?
A civil engineer used a 30-m tape in measuring an inclined distance. The measured length on the slope was recorded to be 459.20 m long.
A civil engineer used a 30-m tape in measuring an inclined distance. The measured length on the slope was recorded to be 459.20 m long. The difference in elevationbetween the initial and the end point was found to be 1.25 m. The 30-m tape is of standard length at a temperature of 10ºC and a pull of 5 kg. During measurement thetemperature reading was 15ºC and the tape was supported at both ends with an applied pull of 7.5 kg....

Accuracy of a laboratory scale. To assess the accuracy of a
laboratory scale, a standard weight that is known to weigh 1 gram
is repeatedly weighed 4 times. The resulting measurements (in
grams) are: 0.95, 1.02, 1.01, 0.98. Assume that the scale weights
when the true weight is 1 gram are normally distributed with sample
standard deviation 0.03. At the 5% significance level, do these
data provide evidence that the scale is accurate? Do the five steps
to hypothesis testing...

When measuring with a pH electrode, several things limit the
accuracy of the measurement. In each of the following situations,
describe what would cause the observed effect:
A. Acid error occurs when the pH is too low. Example, you have a
0.5 M solution of HCl, but your probe provides a measured pH of
0.50
B. Sodium error occurs when the pH is too high. Example, you
have a 0.5 M solution of NaOH, but measure a pH of 13.00...

To investigate the fluid mechanics of swimming, twenty swimmers
each swam a specified distance in a water-filled pool and in a pool
where the water was thickened with food grade guar gum to create a
syrup-like consistency. Velocity, in meters per second, was
recorded and the results are given in the table below.
