The following is a set of hypotheses, some information from one or more samples, and a standard error from a randomization distribution. Test Ho : p = 0.27 vs Ha : p /2 when the samples have n1 = n2 = 50,x1 = 35.5, x2 = 32.8, $1 = 1.23, and $2 = 1.14. The standard error of X1 - X2 from the randomization distribution is 0.24. Find the value of the standardized z-test statistic. Round your answer to two decimal places
