Test the hypothesis that heating increases the diameter at the level of significance 0.01.

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…

Please solve the following attached question and round as needed in parts a and b. In part b, options for H0 and H1 null and alternatives hypotheses are: There is no lack of fit for the model A linear model would fit the data better than a quadratic model A cubic model would fit the data better than a quadratic model An exponential model would fit the data better than a quadratic model There is a lack of fit for the model
