A bioengineering firm was working to increase the yield of eggplant crops, and it developed two promising strains of eggplant. The firm decided to check that Strain A produced less than Strain B by replicating the test on a much larger scale by planting the crops in 5
different fields. The fields were randomly assigned a density at which the seeds were planted, with half of each field growing one of the
two strains. The results of the yields (in pounds per square yard) are shown below. Note: d=(Strain A-Strain B)

Assume that both of the populations are normally distributed. At the 0.10 level of significance, is there sufficient evidence to show that
the yield of Strain A is less than Strain B?
