Hi,

I have a question on how to solve this answer. I have no idea what I need to do. Here's the problem and the questions that need to be solved. An airline company is interested in improving customer satisfaction rate from the 66% currently claimed. The company sponsored a survey of 264 customers and found that 186 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 higher than the claim by the company at a significance level of a= 0.1? Yes or No?
