The variance for seed number is 25.0, and plants outside the plot have mean seed number 15.0.

Question:

The variance for seed number is 25.0, and plants outside the plot have mean seed number 15.0.
The weights, heights, yields, and seed number for 10 plants grown in an experimental plot are given in the table. Each measurement is approximately normally distributed. We wish to determine whether plants in the plot differ from those outside. In each case, state one- and two-tailed alternative hypotheses and find their significance.
