Question: 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
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 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 cm in the existing manufacturing process is the same as the proportion in the new process. At alpha 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 Pvalue. See Step in the Python script. Note that Python methods return two tailed Pvalues. You must report the correct Pvalue based on the alternative hypothesis.
Provide a conclusion and interpretation of the test: Should the null hypothesis be rejected? Why or why not?
