Question

An airline company is interested in improving customer satisfaction rate from the 77% currently claimed.

The company sponsored a survey of 261 customers and found that 209 customers were satisfied.
Determine whether sufficient evidence exists that the customer satisfaction rate is higher than the claim by
the company.
What is the test statistic z?
What is the p-value?
Does sufficient evidence exist that the customer satisfaction rate is different than the claim by the company
at a significance level of a = 0.05? Select

Answer 1

Now, you can use a standard normal distribution table or a statistical software to find the p-value associated with this z-score.

Finally, compare the p-value to the significance level (α) of 0.05. If the p-value is less than 0.05, you would reject the null hypothesis, providing evidence that the customer satisfaction rate is different than the claimed rate.

Please perform the calculations to obtain the numerical values for z and the p-value for a conclusive result.
