Your task is to determine, where possible, if there is a statistically significant difference in these two KPIs between the two depots. Data given: You have been given the daily OTP and SPH performance data for both depots for the past 18 years (assume no changes in technology or management over that timeframe). Each record in the "A TALE OF TWO DEPOTS.xlsx file >> 18_YR_DATA tab" represents a day at the particular depot listed under DEPOT_ALIAS. Deliverable: Conduct your analysis with SPSS and submit a Word document or PDF with answers to the following: 1) OTP: a. Conduct tests to determine if an independent samples t-test can be conducted on the OTP data. That is, does the data violate any assumptions which prevent the independent sample t-test from being conducted? Provide evidence (graphs, any test results) to support your decision. 2) SPH: a. Conduct tests to determine if an independent samples t-test can be conducted on the SPH data. Does it violate any assumptions which prevent the independent sample t-test from being conducted? Provide evidence (graphs, any test results) to support your decision. b. Assuming that 2a allows for the independent samples t-test to be conducted, determine if there is
