When evaluating low birth rate in a particular population there are several factors to consider. These factors include the birth weight of the infant, low birth weight (yes or no), age of the mother, weight of the mother at her mast menstrual cycle. Her race, if she smoked at pregnancy, premature labor, history of hypertension, uterine irritability. And the amount of doctor’s visits during the first trimester.

Statistics Assignment Seven This paper will use inferential statistics to test two different research questions. There will be two different types of statistical test that will be used. The first statistical test will be a Chi-Square for independence and the second statistical test will be a Pearson r test. Both tests will have the seven hypotheses testing steps explained, a descriptive discussion of the variables, possible errors, critique of research methods and implications for research and nursing

Results The Armadillidium Vulgare population had statistically significantly population distributions while under the variety of environmental stimuli they were exposed to (Table 1). At the end of the thermal response experiment, it was documented that a significant portion of the test population had migrated to the cooled testing chamber as opposed to the heated chamber (Figure 1). Although the light stimuli experiment illustrated a weaker preference of environmental stimuli, a major portion of
