Glaucoma is a leading cause of blindness in the United States, N. Ehlers measured the difference in corneal thickness (in microns) between the two eyes of eight patients. Each patient had one eye that had glaucoma and one eye that was normal. The difference was measured as the corneal thickness of normal eye – corneal thickness of eye with Glaucoma. Corneal thickness is important because it can mask an accurate reading of eye pressure. Question: If a participant has the same corneal thickness in their normal eye as the eye with Glaucoma, what would be the value for difference: measured as the corneal thickness of normal eye – corneal thickness of eye with Glaucoma.

Corneal thickness is important because it can mask an accurate reading of eye pressure. Question:If the t statistic falls below the effect size in which we reject the null, but the p value is greater than 0.05. Do i reject the null? As my scenario had no population mean because the differences were recorded, do i set a test value of 10 or keep it at 0?

Each patient had one eye that had glaucoma and one eye that was normal. The difference was measured as the corneal thickness of normal eye – corneal thickness of eye with Glaucoma. Corneal thickness is important because it can mask an accurate reading of eye pressure. Question: Write a report summarizing your findings When writing the report consider that medical staff estimate that a difference of 4.5 microns or more could impact on their ability to interpret eye pressure correctly.
are you able to help me produce a graph which includes all of this Use the data generated in the laboratory to prepare a table and graph of the results, with a written summary. To include: Table of summary results that is mean and SD (standard deviation) only (not individual numbers for each tube) Graph of change in whatever parameter (plot the mean and error bar using the standard deviation) is used to determine the effect on the vegetable on the y-axis against sugar/NaCl concentration on x-axis, put both parameters on one graph. Do a correlation graph so add a correlation, R2 number, find this in Excel – add trendline and under trendline look for more options and at bottom at R2 to graph. Then in discussion use this value to comment on whether or not a correlation between the changes and the findings. Text: short summary of the key findings - NOT what happens for each tube but the general trend of the results and the correlation coefficient. with these set of results Solution…
