Total plasma volume is important in determining the required plasma component in blood replacement therapy for a person undergoing surgery. Plasma volume is influenced by the overall health and physical activity of an individual. Suppose that a random sample of 50 male firefighters are tested and that they have a plasma volume sample mean of x = 37.5 ml/kg (milliliters plasma per kilogram body weight). Assume that ? = 7.20 ml/kg for the distribution of blood plasma.
The average retirement age in America is 62 years old. Gerardo thinks that yoga teachers owners retire at age that is younger than average. The data below shows the results of a survey of yoga teachers about the age where they retired. Assume that the distribution of the population is normal. 49, 65, 66, 65, 51, 65, 51, 47, 57, 60, 66 Download CSV or cut and paste into Desmos E. We want to test Gerardo's claim at the 0.09 level of significance. i) For this study, which type of test should we use? t-test for a population mean ii) The null and alternative hypotheses would be: Но: 62 На: 62 ii) The test statistic is 1.59 (Please round your answer to 2 decimal places.) iii) The p-value = 0.072 (Please round your answer to 3 decimal places.) iv) What is our conclusion regarding the null hypothesis? Explain. The data suggest the population mean number of retire teachers that own a yoga store is not significantly less than 62 years old at 0.09 level, so there is insufficient evidence to…

Total blood volume (in ml) per body weight (in kg) is important in medical research. For healthy adults, the red blood cell volume mean is about ? = 28 ml/kg.† Red blood cell volume that is too low or too high can indicate a medical problem.
