You wish to test the following claim (HaHa) at a significance level of α=0.01α=0.01.

      Ho:μ=77.4Ho:μ=77.4
      Ha:μ>77.4Ha:μ>77.4

You believe the population is normally distributed, but you do not know the standard deviation. You obtain a sample of size n=227n=227 with a mean of M=78.2M=78.2 and a standard deviation of SD=14.1SD=14.1.

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

What is the test statistic for this sample? (Report answer accurate to three decimal places.)
test statistic =
