Type A uncertainties are those
estimated by non-statistical means
estimated by statistical means
estimated by any means
estimated by measurement done by a single operator
The distribution shown in the figure depends on the degree of freedom. The figure shows a
Bionomial Distribution
A Distribution
Chi Square distribution
T distribution
The shaded region of the curve
(More than 1 answer)
is area under the distribution curve
denotes probability beyond the blue vertical line
is 0.0001% of the area under the entire curve
has no meaning
The P-value indicates
a 0.025 chance of finding a value greater than Tcritical
the area of curve in shaded region is 0.025
the shape of the curve is Gaussian
the critical value cannot be found
A suitable Null Hypothesis for the diagram shown is
Ho: μo > μ1
Ho: μo ≠ μ1
Ho: μo = μ1
Ho: μo ≤ μ1
If α = 0.01, the confidence level is

Given these measurement values, 10 12 13 15 10, what is the X Bar and Range?
X Bar = 10
Range = 3
X Bar = 12
Range = 1
X bar = 12
Range = 5
X Bar = 10
Range = 5
The mean of this set of measurement is 50. Looking at the histrogram of the data collected, you can say
The bias is equally distributed
Nothing can be said about the dataset regarding bias
There is some bias in the measurement
There is no bias in the measurement
Given the table on the left. What is the number of sample size of the measurement
50
14
15
undetermine
Look at the table and formula for UCL and LCL. Calculate LCL and UCL given √15 = 3.873.
LCL = 50.0
UCL - 51.0
LCL = 50.10
UCL = 50.35
LCL = 51.00
UCL = 51.10
LCL = 50.55
UCL = 50.65
A set of measurements are plotted as a historgram with a reference value of 50. The diagram indicates
There is definitely no bias in the system
There is definitely some bias in the system
There is uncertain bias in the syste
That we cannot determine the bias
What is the meaning of linearity of a measurement system?
There is no such term used in describing a measurement system
How much difference in standard deviation across all sizes of the part being measured
How much difference in bias across all sizes of the part being measured.
How much difference in mean across all sizes of the part being measured.
Looking at the table, if the null hypothesis is the bias = zero, you can
accept the alternative hypothesis
reject the null hypothesis
accept the null hypothesis
none of the above
Base on the diagram, you can say ..
(more than one answer)
part 10 has a negative bias
Part 6 has no bias
part 2 has no bias
non of the above
Based on the table, you can say for the standard part 2.0000 and part 4.0000
There is no bias for both
The test statistics is unclear
There is bias for 2.000 but not for part 4.000
There is a bias for 2.000 and 4.000
