(ii) Produce bar chart(s) for (a) live born singleton and (b) live born multiple babies according to frequency of babies at each birth weight category that allows an easy comparison between the live born singletons and live born multiple births. (4 marks)

a).

b).

(iii) for babies of singletons, plot a bar chart showing the frequency of birth weight categories for both live born and still born births. Comment on the distribution and comparison of singleton live birth weights to singleton still births. Suggest reasons why still birth weights might be different. (4 marks)

From the graph, the live born singletons surpasse the still born singletons by a large margin. This shows that there is high chances of live born in all categories when the birth is singleton. The success is even more pronounced when the baby weights between 2500-4000 grams.
Still born weights may be different because they are measured for every 1000 deliveries recorded.

iv)Taking the middle value for each birth weight category calculate the mean birth weight and standard deviation, across all singleton live babies. For the category of "999g and under" use 750g as the "middle value" for this category. For the category "5000 or over" use 5250 as the middle value. Calculate the mean birth weight and standard deviation for multiple live babies. Explain the method you used giving formulae. (5 marks)

This method is used since it is the most appropriate for calculating the mean and the standard deviation of a grouped data.

Mean= x.f /n = 46690.36 (singletons) 748 (multiple babies)

Where x is the middle value
F is the frequency
N is the total

SD=√ ∑ (middle value-mean)2 f
= 66395 (singletons) ...

...38) in study groups was additional weak point that may have debased the assumption of similarity of samples, since ignorance of hygienic habits considered major risk factor to be investigated, in this study. The research findings support the hypothesis that therapeutic objectives could be improved, mainly in primary prevention of pneumonia risk factors.

An analysis being intent-to-treat is basically an initial interventional results assignment and not on the intervention ultimately received. This analysis is aimed to avoid a variety of deceptive artifacts that can take place in intervention research. It is broadly utilized in published clinical trials. It offers unbiased comparisons among the intervention groups and also gives information regarding the potential consequences of intervention policy rather than on the possible consequences of particular treatment.
