Internal Code: MAS3305 Biostatistics Assignment: 1) How many observations are in the dataset? 2) What type of variable is apgar5? Give an example of a dichotomous variable in the dataset. 3) Produce a histogram of Systolic Blood Pressure with the normal curve overlaid. 4) Which statement is the most accurate? Use any graphical method to make your assessment. a. The distribution of systolic blood pressure has a very skewed non-normal distribution b. Apart from a few outliers, the distribution of systolic blood pressure is approximately normally distributed c. The distribution of systolic blood pressure is extremely skewed with several large outliers d. The distribution of systolic blood pressure is approximately uniform 5) Babies with an APGAR score of 8 at 5 minutes are generally considered to be in good health. Babies with a score less than 8 may need immediate specialized care. Generate a new variable ‘apgarcat’ which classifies the babies into two categories: those with an APGAR score of 8 or more and those with an APGAR score of less than 8. Show the Stata code used to create the variable. 6) What percentage of babies might need immediate special care i.e. have an APGAR score of less than 8? 7) Create a 2×2 contingency table of tox by apgarcat with row and column percentages. What percentage of babies born to mothers with a toxaemia diagnosis had an APGAR score of less than 8? PART B: 8) What percentage of infants would be expected to have a gestational age of more than 35 weeks? 9) What percentage of infants would be expected to have a gestational age of between 26 and 33 weeks? 10) We would expect approximately 99% of the babies to have a gestational age that falls between [?] weeks and [?] weeks. PART C: 11) What does the p-value of p<.0001 indicate? a. There is insufficient evidence to support the null hypothesis that there is no difference in weight loss between the support and advice groups b. There is sufficient evidence to support the alternate hypothesis that there is a difference in weight loss between the support and advice groups c. There is sufficient evidence to accept the null hypothesis that there is no difference in weight loss between the support and advice groups d. There is insufficient evidence to accept the null hypothesis that there is no difference in weight loss between the support and advice groups 24 total views, 2 views today
