Hypotheses and summary sample statistics are given for a test for a difference in means. Assume that the conditions are met and the underlying distributions are approximately normal. TestH0:1=2vsHa:1<2using sample results:
n1=50,x1=42,s1=9.6andn2=40,x2=49,s2=12.1.
Find the value of thet-test statistic and then use thet-distribution to find thep-value. Round your answers to three decimal places. test statistic =
p-value =
