STEP 5: COLLECTING THE DATA AND CALCULATING THE TEST STATISTIC Yоu аre evаluаting the perfоrmance оf one of the funds held by Florida Retirement System (FRS). FRS's mean performance over the last 5 years is shown in the table below (2017-2021). In 2022, FRS's investments have been managed under the guidance of DELTA Advisors, and they finally achieved an annual return of [r6]%. You are tasked to write a report on whether or not FRS's performance for 2022 is (statistically) different from the previous years (2017-2021). In order to get the t-critical-value (your threshold to reject the Null), and your t-statistic (the t-"value" that corresponds to your actual tested performance of an annual return of [r6]%), you need to calculate the moments of FRS's return distribution (specifically: Mean, Variance/Standard Deviation). Year Return Latest 2022 [r6]% Historical 2021 [r5]% 2020 [r4]% 2019 [r3]% 2018 [r2]% 2017 [r1]% A. You quickly estimate the Mean and write it down (After all, since the data corresponds to historical values, this is the same as the Arithmetic Mean = Average). B. You estimate the Standard Deviation, and since the number of years in your sample = only five (small), you consider that this is a sample. C. You estimate the Standard Error, which you get dividing the standard deviation by the square root of N. The t-statistic (t-"value" estimated from your data) is __________. Please type your answer as percentage and not as decimal (e.g., 5.2 and not 0.0502). Round to the nearest two decimals, if needed.
