A recent study reported the following data on the occurrence of salmonella in chicken of three different types: (type 1) supermarket chilled, (type 2) supermarket frozen, (type 3) wet market fresh slaughtered. # of samples with salmonella total sample size Type 1 Type 2 Type 3 120 a. If you were to select two chickens from the sample without replacement, what is the probability that both had salmonella? (104/240)+(103/239) 2*(104/240) (104/240)*(103/240) (104/240)^2 (104/240)*(103/239) Points possible: 3 b. Consider performing a test of independence between type of chicken and salmonella occurrence. b1. Under the null hypothesis, what is the expected value for the number of type 3 chicken which do not have salmonella? 34 68 52 2,834 MAY 7 K Ctv 4. MacBook Pro O *
