The test statistic's value is $2 n1 n2 =(54.3-48) /sqrt(14.9^2/17 + 5.7^2/13) = 1.597. What is the test statistic for this sample? Oz-test independent samples t-test, df = 21.65 (round to 22) O paired samples t-test, df = 21.65 (round to 22) What is the p-value for this sample? For this calculation, use the degrees of freedom given in the answer above. (Report answer accurate to four decimal places.) p-value =
