The makers of Mama’s Home-Made Salsa are concerned about the quality of their product. The particular trait of concern is the thickness of the salsa in each jar.
a. Discuss a plan by which the managers might determine the percentage of jars of salsa believed to have an unacceptable thickness by potential purchasers. (1) Define the sampling procedure to be used, (2) the randomization method to be used to select the sample, and (3) the measurement to be obtained.
b. Explain why it would or wouldn’t be feasible (or, perhaps, possible) to take a census to address this issue.
