You wish to test the following claim (Ha) at a significance level of a = 0.10. H.: H1 – 42 = 0 Ha: H1 – 42 > 0 You obtain a sample of size n1 the first population. You obtain a sample of size n2 = 78 with a mean of ¤2 of 82 = 7.2 from the second population. = 17.1 from = 46.7 and a standard deviation 65 with a mean of ¤ = 54.9 and a standard deviation of s1 You will need to determine whether or not to pool so you will use the correct df. What is the critical value for this test? Report answer accurate to three decimal places. critical value =
