You wish to test the following claim (H1) at a significance level of α=0.1.

      Ho:μ=62.8
      H1:μ≠62.8

You believe the population is normally distributed, but you do not know the standard deviation. You obtain a sample of size n=7 with a mean of ¯x=69 and a standard deviation of s=18.2.

What is the critical value for this test? (Report answer accurate to three decimal places.)
critical value = ±
