Steps to Hypotheses Testing

Complete the Assignment Worksheet provided in the following attachment. Questions are related to the steps required to interpret statistical results that either reject or fail to reject a null hypothesis.

Research Scenario

Hemoglobin levels (g/dL) from the general population of adult men form a normal distribution with μ = 15.3 and σ = 0.95. 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 men who followed a vegan or vegetarian diet. The average hemoglobin level (g/dL) for this sample was x̅ = 13.2. Do these data indicate that following a vegan or vegetarian diet has a significant effect on hemoglobin levels? Test with p=.05.
