Several studies have shown that vegans and vegetarians suffer from lower than normal hemoglobin levels, which indicates anemia. Using clinical data, a researcher measured hemoglobin levels from a sample of n = 100 adult women who followed a vegan or vegetarian diet. The average hemoglobin level (g/dL) for this sample was x x = 12.5. Do these data indicate that following a vegan or vegetarian diet has a significant effect on hemoglobin levels?

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
