Sammy's Salsa, a small local company, produces 20 cases of salsa a day. Each case contains 12 jars and is imprinted with a code indicating the date and batch number. To help maintain consistency, at the end of each day, Sammy selects three bottles of salsa, weighs the contents, and tastes the product. Help Sammy select the sample jars. Today's cases are coded 07N61 through 07N80. Complete parts a) through c) below.

c) Did you use a simple random sample? Explain. O A. Yes, a simple random sample was used because the sampling method gives each combination of jars an equal chance of being selected. O B. Yes, a simple random sample was used because the sampling method gives each jar an equal chance of being selected. O C. No, a simple random sample was not used because the sampling method does not give each jar an equal chance of being selected. Stratified random sampling was used. O D. No, a simple random sample was not used because the sampling method does not give each combination of jars an equal chance of being selected. Multistage sampling was used.

Today's cases are coded 07N61 through 07N80. Complete parts a) through c) below. a) Carefully explain your sampling strategy. Choose the correct answer below. OA. Select one jar randomly from each case. B. Select the most convenient case. Then select the first three jars from the case. OC. Select three cases at random. Then select one jar randomly from each case. OD. Select one case at random. Then select three jars randomly from the case. b) Show how to use random numbers to pick the three jars for testing. Choose the correct answer below. A. Use random numbers to choose one case from numbers 61 through 80. Then use random numbers between 1 and 12 to select three jars from the case. B. Use random numbers to choose one case from numbers 1 through 12. Then use random numbers between 61 and 80 to select three jars from the case. c. Use random numbers to choose three cases from numbers 61 through 80. Then use random numbers between 1 and 12 to select the jar from each case. D. Use random numbers to choose three cases from numbers 1 through 12. Then use random numbers between 61 and 80 to select the jar from each case. c) Did you use a simple random sample? Explain. OA.
