1Based on Monday 2/28 lectureSuppose that we want to perform a block design experiment.Our sample is divided into five blocks, eachwith four experimental units.However, we have five treatments to test, so we cannot use a randomizedcomplete block design.Can we create a balanced incomplete block design (BIBD) instead?a.How many replicates will we see of each treatment?b.In how many blocks will each pair of treatments be compared?c.I have begun to sketch the experimental design below.In block 1, I will compare treatments 1, 2,3, and 4.Finish creating the BIBD
