A random sample of 31
31 waiting times (in minutes) before patients saw a medical professional in a hospital's minor emergency department had a variance of 0.25 minutes. After a new admissions procedure was implemented, a random sample of 21 waiting times had a variance of 0.16 minute.At α = .05. what's the claim and state Upper H0 and Upper H Ha. Let σ21 represent the initial variance and σ22 represent the variance for the new process.
Also, calculate the critical F-value,the rejection region for the f-test, and the test statistic.
H0: σ 1 2 < σ 2 2 Ha: σ 1 2... View the full answer
