I need a IB Biology SL IA. Word amount = around 2500 words. MLA citations. The experiment’s data can be improvised, and data in processed data should be put in chi-aquares (all calculations should be vividly written).

Introduction should be full explanation about the auditory system, can sex and age determine the auditory system’s ability to perform, what is Hz, My experiment was supposed to be gathering 10 groups of people= 5 male 5 female, and then each of the 5 male and female groups are separated into ages: 8-14 15-21 36-42 57-63 76-82 years. The process of gathering each person, playing sounds and asking to repeat each of 5 words, recording it in a table. I played 5 different sounds.(I need help finding the such 5 different Hz sounds (5 different words), as I need to input the links in the IA). 5 sounds each had a difference word pronounced at different Hz. After each sound played, the person was asked to repeat the word. This was to test if the hearing system of the person heard the word at the given Hz. The data collected was just tables with yes/no (was the sound correctly heard or not, if for example person said bead instead of bead- it is incorrect=no in result table). The experiment’s aim was to determine the auditory system across the years and sex. Does the result support the Null hypothesis and overall hyppothesis? Is there a trend? Also, there needs to be an example of a paper each person signed(a permission to conduct experiment with the person and understanding that the results will be assesed and used further).
