Com E.g.: Doctors at a given hospital want to know if their heart surgery and recovery program allows for their patients to possess typical myocardial blood flow during bicycle exercise. The doctors take a random sample of 8 of their patients and measure their myocardial blood flow (MBF) during bicycle exercise. Their doctors know that healthy men should have an average myocardial blood flow (MBF) during bicycle exercise of 5.15. Here the doctors can use a one-sample t-test.

Notice how the doctors need to set the test value to 5.15 and select the nature of their alternative hypothesis! Also notice that the doctors can obtain a 95% confidence interval around their point-estimate, descriptive statistics for their sample and generate a Q-Q plot! Q-Q plots Standardized Residuals 0.5 1.0 1.5 Theoretical Quantiles 3) Please perform a one-sample t-test by hand using output from this table and interpret the results. If there is a significant difference, make sure to interpret the point estimate relative to the null in the context of the hypothesis test. a) First locate of then go to top if its two-tailed or one-tailed and you get t-value
