Exercise U 5.1 Independent random sample of 36 and 45 observations are drawn from two quantitive populations, 1 and 2, respectively. The sample data summary is shown here: Sample 1 Sample 2 Sample size 36 45 Sample mean 1.24 1.31 Sample variance 0.0560 0.0540 Do the data present sufficient evidence to indicate that the mean for population 1 is smaller than the mean for population 2? Use p=value and Critical value approaches and explain your conclusions
