I am having trouble with finding the solution to the problems.

(a) A host on a cruise ship wants to collect data on the time passengers spend at various activities on board. Which of the following best describes a systematic sample of passengers? The host takes a list of the passengers and selects every 3" passenger until 78 passengers are selected. The host forms groups of 13 passengers based on the passengers' ages. Then, he randomly chooses 6 groups and selects all of the passengers in these groups. O The host selects the first 78 passengers who board because these passengers are easily accessible. (b) A consultant wants to ask workers at a factory about the workers' job satisfaction. Which of the following best describes a random sample of workers? O The consultant assigns each worker a different number. Using a random number table, he draws 50 of those numbers at random. Then, the consultant selects the workers assigned to the drawn numbers. Every set of 50 workers is equally likely to be drawn using the random number table. O The consultant takes a list of the workers and selects every 5" worker until 50 workers are selected. O All of the workers on the second floor of the factory building are easily accessible. So, the consultant selects the first 50 workers from the second floor to arrive at work on a particular day. (c) A manager at a bus company wants to survey employees about the new uniforms. Which of the following best describes a cluster sample of employees? The manager uses a computer program to draw 60 employees at random and selects these employees. Every set of 60 employees is equally O likely to be drawn by the computer program. The manager forms 5 groups of employees based on the departments the employees are in. Then, she selects 12 employees at random from each aroun. Submit As
