The following statistics were calculated: 1 – Calculate the pooled estimate of the variance for the population. (3 points) 2 – Find the 95% confidence interval for µ1 -µ2 using the pooled estimate of the variance for the populations

Independent random samples were selected from two normal populations. The following statistics were calculated: 1 – Calculate the pooled estimate of the variance for the population. (3 points) 2 – Find the 95% confidence interval for µ1 -µ2 using the pooled estimate of the variance for the populations
