Blood pressure: A blood pressure measurement consists of two numbers: the systolic pressure, which is the maximum pressure taken when the heart iscontracting, and the diastolic pressure, which is the minimum pressure taken at the beginning of the heartbeat. Blood pressures were measured, in millimetersof mercury (mmHg), for a sample of 10 adults. The following table presents the results. Use a TI-84 calculator to answer the following.DiastolicSystolicDiastolicSystolic1348711811513076113771167012377133911196911275Based on results published in the Journal of Human HypertensionSend data to ExcelIf the systolic pressures of two patients differ by 16 millimeters, by how much would you predict their diastolic pressures to differ?

Do various occupational groups differ in their diets? A British study of this question compared 98 drivers and 83 conductors of London double-decker buses. The conductors' jobs require more physical activity. The article reporting the study gives the data as "Mean daily consumption (+ se)." Some of the study results appear below. Drivers Total calories 2821 +44 Alcohol (grams) 0.24 0.06 Conductors 2844 +48 0.39 ± 0.11 Construct a 99% confidence interval for the difference in mean daily alcohol consumption between drivers and conductors.
The data found below measure the amounts of greenhouse gas emissions from three types of vehicles. The measurements are in tons per year, expressed as CO2 equivalents. Use a 0.05 significance level to test the claim that the different types of vehicle have the same mean amount of greenhouse gas emissions. Based on the results, does the type of vehicle appear to affect the amount of greenhouse gas emissions?

The age of a tree can be determined by counting each annual growth ring in the trunk of the tree. A common measure of the size of a tree is the "diameter at breast height" DBH. "Breast height" is defined as 4 ½ feet above the uphill side of the tree.
