A : When cigarettes are burned, one by-product in the smoke is carbon monoxide. Data is collected to determine whether the carbon monoxide emission can be predicted by the nicotine level of the cigarette. It is determined that the relationship is approximately linear when we predict carbon monoxide, C, from the nicotine level, N. Both variables

Durrade et al. ( 2023) examined the effect of hours of sleep on eating behavior. They assigned one group of adolescents ( 14- to 17-year olds) to Short Sleep (6-5 hours in bed) and one to Healthy sleep (8.5 hours in bed) for S nights. For this example, we will look at the number of sugary drinks consumed per day (e-g., soda, Pappucano, chocolate

PhD Application Research Proposal. Title: Unique Solutions to Non-Local Partial Differential Equations (ODE's/PDE's) Using Various Fixed Point Theories Introduction Non-local ODE's/PDE's are a significant area of study in mathematical and physical sciences due to their ability to model complex phenomena that local ODE's/PDE's cannot capture.
