The Rathburn Manufacturing Company makes electric wiring, which it sells to contractors in the construction industry. Approximately 900 electric contractors purchase wire from Rathburn annually. Rathburn’s director of marketing wants to determine electric contractors’ satisfaction with Rathburn’s wire. He developed a questionnaire that yields a satisfaction score between 10 and 50 for participant responses. A random sample of 35 of the 900 contractors is asked to complete a satisfaction survey.The satisfaction scores for the 35 participants are averaged to produce a mean satisfaction score.
To calculate the mean satisfaction score for the 35 participants, you will need to sum up all of their individual satisfaction scores and divide it by the number of participants.
Here are the steps to calculate the mean satisfaction score:
1. Add up all the satisfaction scores of the 35 participants.
2. Divide the sum by 35 (the number of participants).
3. The result will be the mean satisfaction score.
Let's say the satisfaction scores for the 35 participants are as follows:
Participant 1: 40
Participant 2: 45
Participant 3: 38
Participant 4: 42
... (and so on)
Now, you would add up all of these satisfaction scores:
40 + 45 + 38 + 42 + ... (and so on) = Sum
After calculating the sum, you would divide it by 35:
Mean satisfaction score = Sum / 35
Please note that I provided a simplified example of how to calculate the mean satisfaction score. In reality, you would need to know the exact satisfaction scores of the 35 participants to perform the calculation accurately.
