A randomly sampled group of patients at a major U.S. regional hospital became part of a nutrition study on dietary habits. Part of the study consisted of a 50-question survey asking about types of foods consumed. Each question was scored on a scale from one: most unhealthy behavior, to five: most healthy behavior. The answers were summed and averaged. The population of interest is the patients at the regional hospital. The current survey was implemented after patients were subjected to this education, and 100 patients were included in the sample. The t test for the hypotheses Hoμ = 2.9 versus Haμ> 2.9 was 1 = 2.88.
the p value is significant at:
a=0.01
all of the answer options are correct
a=0.05
a=0.1
