Two different technicians (Tech A and Tech B) each measured the cardiac output for a sample of 26 patients using Doppler Echocardiography. The supervisor would like to use this paired data to assess inter-rater reliability by testing if the population mean difference in cardiac output is 0 (no difference on average) versus the alternative that there is a difference. The hypotheses to be tested are: H₀: μ_d = 0versus H_a: μ_d ≠ 0, using a 10% significance level.

A- The sample mean difference in cardiac output (Tech A less Tech B) was 1.8 standard errors above 0. Provide a complete sketch of the p-value that the supervisor can include in her report. You can use the pvalue shiny app which will give the exact p-value (and allow you to add your name to the graph when you type 'y' to save the graph to your desktop), or make a complete by hand sketch and provide the p-value (bounds). Make sure to include a title for and include your name with your graph.

A study was conducted by the Department of Zoology at the Virginia Tech to estimate the difference in the amount of the chemical orthophosphorus measured at two different stations on the James River. Orthophosphorus was measured in milligrams per liter. Fifteen Specimens were collected from station 1, and 12 specimens were obtained from station 2. The 15 specimens from station 1 had and an average orthophosphorus content of 3.84 milligrams per liter and a standard deviation of 3.07 milligrams per...
