You wish to test the following claim (H11) at a significance level of =0.005=0.005. Ho:=89.6:=89.6 H1:<89.61:<89.6 You believe the population is normally distributed, but you do not know the standard deviation. You obtain a sample of size n=25=25 with a mean of x=86.9=86.9 and a standard deviation of s=19.3=19.3. What is the critical value for this test? (Report answer accurate to three decimal places.) critical value =
