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.

test-statistic = -2.08

two-tailed p-value = 0.0377

1. Include the test statistic and the P-value. (Note that Python methods return two-tailed P-values. You must report the correct P-value based on the alternative hypothesis).

2. Provide a conclusion and interpretation of the test: Should the null hypothesis be rejected? Why or why not?
