a) Construct a 95% confidence interval to estimate the difference in means between the populations from which Sample 1 and 2 were drawn. The difference is defined as Sample 1 - Sample UCLa = LCL = (Round to two decimal places as needed.) b) What conclusions can be made based on these results? The interval zero, so there enough evidence to conclude that there is a difference in means between the populations from which Sample 1 and 2 were drawn.
