A prior survey of patients had found the mean healthy eating score for the population of patients to be µ = 2.8. The hospital nutritionist decided that patients might benefit from nutrition education. The current survey was implemented after patients were subjected to this education, and it produced the following sample statistics for the 20 patients sampled: x (bar) = 3.3 and s = 1.2. We would like to know if the education program improved eating habits. What are the null and alternative hypotheses: Group of answer choices H0: µ = 3.3, Ha: µ > 2.8 H0: µ = 2.8, Ha: µ < 2.8 H0: µ = 3.3, Ha: µ > 3.3 H0: µ = 2.8, Ha: µ = 3.3 H0: µ = 3.3, Ha: µ ≠ 3.3 H0: µ = 2.8, Ha: µ ≠ 2.8 H0: µ = 2.8, Ha: µ > 2.8

A random sample of patients at a hospital became part of a nutrition study on dietary habits. Part of the study consisted of a survey asking about types of foods consumed. Each of the questions was scored on a scale from one (most unhealthy) to five (most healthy ). The answers were averaged. A prior study conducted at the hospital showed that such averages follow a
