Run the following program to generate a SAS data set DOSE, showing the number of patients having significant pain and those not having significant pain for each of three doses of medication. Compute the regular chi-square statistics and a chi-square for a test of trend. Do the proportions of patients having significant pain show a significant downward trend? Notice that the values for PAIN and DOSE are already in the correct order for your table.
