Estimate the difference between the mean yields by a 95% confidence interval. See problem below in the attached photo.

To test two promising new lines of hybrid corn under normal farming conditions, a seed company selected 8 farms at random and planted both lines in experimental plots on each farm. The yields (converted to bushels per acre) for the eight locations were Line A: 58 87 58 93 83 82 78 79 Line B: 80 81 58 88 78 85 75 70 Assuming that the two yields are jointly normally distributed, estimate the difference between the mean yields (um-Hm yLineB) by a 95% confidence interval.
