Need help with the following Stat question, thank you! Use the t-distribution and the sample results to complete the test of the hypotheses. Use a 5 % significance level. Assume the resultscome from a random sample, and if the sample size is small, assume the underlying distribution is relatively normal.Test Hoμ = 15 vs Haμ> 15 using the sample results = 17.2, s = 6.4, with n = 40.(a) Give the test statistic and the p-value.Round your answer for the test statistic to two decimal places and your answer for the p-value to three decimal places.test statistic = ip-value = ieTextbook and Media(b) What is the conclusion?O Reject Ho.O Do not reject Ho.eTextbook and Media

Given that Level of significance (α) = 0.05 (5%) Sample size (n) = 40 Sample mean (x¯) = 17.2…

Answered: Use the t-distribution and the sample…

I need to see if I am doing these problems correctly. I am more of a handwritten person so if you can show me how to write these out I would appreciate it for our teacher only shows us how to use a calculator. Nationally, patients who go to the emergency room wait an average of 7 hours to be admitted into the hospital. Do patients at rural hospitals have a lower waiting time? The 15 randomly selected patients who went to the emergency room at rural hospitals waited an average of 5.9 hours to be admitted into the hospital. The standard deviation for these 15 patients was 1.4 hours. What can be concluded at the the αα = 0.05 level of significance level of significance? For this study, we should use The null and alternative hypotheses would be: H0:H0: H1:H1: The test statistic = (please show your answer to 3 decimal places.) The p-value = (Please show your answer to 4 decimal places.) The p-value is αα Based on this, we should…
