Airline Customer Satisfaction Rate Survey Analysis
Is the Airline Company's Customer Satisfaction Rate Higher Than Claimed?
Based on a survey sponsored by the airline company, 221 out of 278 customers were satisfied. Does this data provide enough evidence to support the claim that the customer satisfaction rate is higher than the 77% currently claimed by the company?
Analysis of Survey Results
The airline's customer satisfaction rate based on the survey is 79.5%, which is higher than the company's claimed rate. However, a statistical hypothesis test is needed to determine the significance of this difference.
In analyzing the survey results, we can calculate the percentage of satisfied customers by dividing the number of satisfied customers (221) by the total survey sample size (278) and multiplying by 100. This gives us a customer satisfaction rate of 79.5%.
The observed satisfaction rate from the survey is higher than the company's claimed rate of 77%, suggesting that there may be a positive trend in customer satisfaction. However, to confirm whether this difference is statistically significant, a hypothesis test such as a t-test or z-test for proportion would be necessary.
Conducting a statistical test will help determine if the observed increase to 79.5% could have occurred due to random chance or if it reflects a true improvement in customer satisfaction. It is important to validate the findings with statistical analysis to make informed decisions based on the survey data.
