Analysis of a random sample consisting of m=20 specimens of cold rolled steel have an average strength of x_bar = 29.8 ksi. Analysis of a random sample consisting of n=25 specimens of two-sided galvanized steel yielded a sample average strength of y_bar = 34.7 ksi.  Assuming normal populations with standard deviations of sigma_x=4, and sigma_y=5. In doing a hypothesis test to see if the two types of steel strengths are different, calculate the test statistic?
