Adapted From Triola, et al., 2018. Biostatistics, pg. 524. Nurses at a veteran’s hospital in Massachusetts, noticed an unusually high number of deaths at times when a certain nurse (KG) was working. They also noticed missing supplies of the drug epinephrine, a synthetic adrenaline that stimulates the heart. Was arrested and charged with 4 counts of murder and 2 counts of attempted murder. The following contingency table was introduced at KG’s trial. Do you think it was introduced by prosecution or the defense? That is, does it suggest anything about KG’s guilt or innocence? What would the Ho and Ha be? and would we reject the null hypothesis? would the Ho and Ha be this?: Ho KG Is guilty Ha KG is innocent
