A hospital was concerned about reducing its wait time. A targeted wait time goal of 25 minutes was set. After implementing an improvement framework and process, a sample of 329 patients showed the mean wait time was 23.15 minutes, with a standard deviation of 16.98 minutes.. a. If you test the null hypothesis at the 0.05 level of significance, is there evidence that the population mean wait time is less than 25 minutes? State the null and alternative hypotheses. O A. Ho: μ> 25 H₁: μ<25 O D. Ho: μ ≥25 H₁:μ#25 Find the test statistic for this hypothesis test. *STAT = B. Ho: μ<25 H₁:μ>25 E. Ho: μ< 25 H₁:μ ≥25 (Type an integer or a decimal. Round to two decimal places as needed.) Is there sufficient evidence to reject the null hypothesis? (Use a 0.05 level of significance.) C. Ho: μ#25 H₁:μ ≥ 25 OF. Ho: μ ≥25 H₁: μ<25 A. Reject the null hypothesis. There is sufficient evidence at the 0.05 level of significance that the population mean wait time is greater than 25 minutes. B. Reject the null hypothesis. There is sufficient evidence at the 0.05 level of significance that the population mean wait time is less than 25 minutes. OC. Do not reject the null hypothesis.
