Question
Hypodermic needles are produced in a manufacturing process. The quality feature to be
monitored is the outside diameter (in mm) for which the target value=0.8 is specified.
We assume that the outside diameter is due to production-related variations Mμ, 02)-
distributed.
In the course of monitoring the process, a test random sample is taken from the ongoing
production N=10 needles removed. The sample mean (arithmetic mean) is 0.827, which
is the sample standard deviation (empirical standard deviation).s(x) = 0.05
a) Are the data compatible with the hypothesis that the target value0=0.8 is maintained on
average in the overall production? Test this
HO: με μό
1:06μ
to the significance levela- 5%. The quantiles required for the test are included Rto
determine. In your solution, indicate the command used for this.
against
b) How small or how large should the sample mean of a sample with a size of N=10 with the
same sample standard deviation, so that the null hypothesis in part a) is rejected?
