Based on the sample of 50 that you collected, is there evidence to suggest that the average diameter is greater than 2.30 cm? Perform a hypothesis test for the population mean at alpha : 0.01. - Define the null and alternative hypothesis forthis test in mathematical terms and in words. - Report the level ofsignicance. - Include the test statistic and the P-value. See Step 3 in the Python script. (Note that Python methods return two tailed Pvalues. You must report the correct Pvalue based on the alternative hypothesis.} z-test hypothesis :est for populacion mean tescestacistic = 0.61 two tai1ed p-value = 0.5438 - Provide your conclusion and interpretation ofthe results.
