The following data on work of adhesion measurements (in mJ/m^2) for samples of ultra-high performance concrete adhered to two types of substrates: Substrate Observations
Steel: 107.1 109.5 107.4 106.8 108.1
Glass: 122.4 124.6 121.6 120.6 123.3

Assuming that both samples were selected from normal distributions, carry out a test of hypotheses to decide whether the true average work of adhesion for the glass substrate is more than 12 mJ/m^2 higher than that for the steel substrate.
