You wish to test the following claim (HaHa) at a significance level of α=0.10

      Ho:μ=79.4
      Ha:μ≠79.4

You believe the population is normally distributed, but you do not know the standard deviation. You obtain asample
of size n=20 with a mean of x=87 and a standard deviation of s=13.6

a.) This test is a.)left tailed b.)right tailed c.)two tailed

b.) At α=α=0.10, the critical value = ± (use 3 decimal places)

c.) The test statistic =  (use 2 decimal places)

d.) The test statistic is...
