Suppose that you wanted to determine if Santa Ana residents have better FICO Scores than the U.S. average of 540. You collect a simple random sample of 1000 Santa Ana residents and find a sample mean of 575. The population standard deviation for all FICO scores is 41. Choose the null and alternative hypothesis for the test.

Question
Suppose that you wanted to determine if Santa Ana residents have better FICO Scores than the U.S.
average of 540. You collect a simple random sample of 1000 Santa Ana residents and find a sample
mean of 575. The population standard deviation for all FICO scores is 41.
Choose the null and alternative hypothesis for the test.
H_o is the null hypothesis
H a is the alternative
O H_o:u>.540, H_a: u-540
O Ho:u-540, H_a: u<540
O Ho:p-540, H_a: p>540
O Ho:u-.540, H a: u>540
O H_o u<540, H_a: u>540
