Independent random samples of 36 and 46 observations are drawn from two quantitative populations, 1 and 2, respectively. The sample data summary is shown here.
Sample 1 | Sample 2 | |
---|---|---|
Sample Size | 36 | 46 |
Sample Mean | 1.29 | 1.32 |
Sample Variance | 0.0590 | 0.0530 |
Do the data present sufficient evidence to indicate that the mean for population 1 is smaller than the mean for population 2? Use one of the two methods of testing presented in this section. (Round your answer to two decimal places.)
