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: μd = 0versus Ha: μd ≠ 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.

Two quality control technicians measured the surface finish of a
metal part. Measurements are in the following table. Assume that
the data are normally distributed. (a) State and test the
hypothesis that the mean surface finish measurements made by the
two technicians are equal at alpha = 0.05 assuming equal variances.
(b) State and test the hypothesis that the variances are equal at
alpha = 0.05 to verify the assumption of equal variances. Explains
the steps to complete this using...

2 parts: Part B is different numbers
a.)Each extra worker produces two extra units of output up to 4
workers. After 4 workers, each extra worker produces one extra unit
of output. Draw the total product, average product of labor and
marginal product of labor curves on two graphs.
b.)Suppose inputs are only substitutable at two units of labor
for every one unit of capital. Assume that the production function
q = f(L, K) has constant returns to scale and...

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.
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...
