HACC Statistics the Level of Significance Question
Recently, the factory began a new production line that is more
efficient than the existing production line. However, the factory still
needs ball bearings to meet the same specifications. To compare the
accuracy of the new process against the existing process, the factory
decides to take two random samples of ball bearings. The first sample is
of 50 randomly selected ball bearings from the existing production
line, and the second sample is of 50 randomly selected ball bearings
produced from the new production line. For each sample, the diameters of
the ball bearings were measured.The two samples will be generated using Python’s numpy module. These
data sets will be unique to you, and therefore your answers will be
unique as well. Run Step 1 in the Python script to generate your unique
sample data.Suppose that the factory claims that the proportion of ball bearings
with diameter values less than 2.20 cm in the existing manufacturing
process is the same as the proportion in the new process. At alpha=0.05,
is there enough evidence that the two proportions are the same? Perform
a hypothesis test for the difference between two population proportions
to test this claim.In your initial post, address the following items:Define the null and alternative hypotheses in mathematical terms as well as in words.Identify the level of significance.Include the test statistic and the P-value. See Step 2 in the Python
script. (Note that Python methods return two tailed P-values. You must
report the correct P-value based on the alternative hypothesis.)Provide a conclusion and interpretation of the test: Should the null hypothesis be rejected? Why or why not?
