When we use hypothesis testing, we are trying to achieve the goal of accepting or rejecting a null hypothesis. Overall, we want to configure whether the initial hypothesis is true. As is the case here, we hope to see if the average birth weight of women in the sample baby birth weight is greater than 5 pounds. Additionally, we must determine whether there is sufficient evidence to prove our hypothesis about what we intend to measure. We must use hypothesis testing here to draw inferences about a population from data acquired from our sample of 189 women. Therefore, hypothesis testing uses data to decide whether or not to support the determined hypothesis. Also, in this case we are conducting an upper tail test. According to Dr. Mirabella (2011, p. 4-5), “An upper tail test is one in which the alternative hypothesis tests whether the sample mean is greater than the hypothesized value.” Even more so, the p-value in our question is lower than the set significance level and therefore we must reject the null hypothesis. So, this shows that the average birth weight of the baby is more than 5.0 pounds. Furthermore, with hypothesis testing we are able to evaluate the credibility of a hypothesis on a population. Hypothesis testing helps you evaluate the probability of something happening. According to Bangdiwala (2014, p. 98) states that: “We usually use the statistical hypothesis testing framework to address such questions. Within this framework, we establish two complementary hypotheses: a “null” hypothesis (H0) and an “alternative” hypothesis (H1). These are mutually exclusive (both cannot occur) and exhaustive (these are the only two possible situations). So, one of the hypos...... middle of paper ......ht. Other factors that contribute to babies being born at a healthy weight or in the normal range contribute to the mother's weight both before and during pregnancy. Additionally, it is essential to get enough adequate nutrients to ensure a healthy birth weight. Also, your prenatal health is important and make sure you don't smoke, drink or have other risk factors such as high blood pressure that can cause problems during your pregnancy and for your baby. Additionally, a baby's race can contribute to babies being born with normal birth weights. Children born Caucasian tend to be larger than black children or children of other ethnicities. Additionally, a low birth weight baby is considered less than 5.5 pounds and a high birth weight is more than 8.8 pounds (“Birth Weight,” 2016). However, a normal birth weight can be 5.5 pounds and above.
