STEPS 2 TO 4: CHOOSING TEST, SPECIFYING SIGNIFICANCE LEVEL AND STATING THE DECISION RULE 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) higher compared to the previous years (2017-2021). For this problem, you choose a 10% significance level (which is the same as 90% confidence interval). What is the t-critical value (t-"value" at which you reject the null)? Hint: Is this a one-sided problem or two-sided problem? .... and keep in mind you are relying on the t-critical and not z-value.
