• source of topic 4 Mazurek, D. and Wyka, J. (2015) 'Down syndrome - genetic and nutritional aspects of accompanying disorders', Roczniki Panstwowego Zakladu Higieny, vol.66, no.3, pp.189-94.
• .Find the number of live births in 1940 for women in the maternal age ranges: under 20, 25 to 29 and 35 to 39. Repeat this for the most recently presented year, then for the year of your birth and for two other years that are in different decades - In total, you should have collected data for five different years.(done please double check I've done correctly)
• ii.You were then required to plot a computer-generated x-y scatter graph showing the number of live births for the selected age ranges and birth years, in chronological order (an example of how your graph might look is provided within the activity).done please double check I've done correctly)

Answering this question

• a.Plot your dataset in the form of a line graph using a computer programme to generate the x-y scatter graph. Your graph should have a title, a legend and each axis labelled appropriately. You should also present your dataset in the form of a table.
• b.Using the information presented in your graph and table, answer the following questions:
  • i.What trend is seen over time in the number of births to women in the different age categories?
  • ii.Based on the information presented in Topic 4, what is your prediction for the incidence of Down's syndrome? Briefly, explain your reasoning. ( can someone explain please i know that the most DS is a common genetic disorders and occurs in 1 out of every 600-700births )
