This statistics assignment, completed by Onyema Kelechi Stanley, addresses multiple data analysis problems using R code and statistical tests. The assignment includes detailed analyses of fish length and parasite weight, exploring relationships using scatter plots, linear regression, and hypothesis testing. It investigates the impact of fish length and liver weight on parasite weight, providing interpretations of coefficients, p-values, and R-squared values. The analysis extends to comparing relative liver and parasite weights using logistic regression, examining normality and fulfilling test assumptions. Furthermore, the assignment encompasses t-tests to compare gonad and parasite weights between sexes, providing statistical results. The assignment also includes chi-squared tests to analyze sex ratios and the relationship between plant regeneration methods and species classification. Detailed R code, including plots and statistical summaries, supports all analyses, with conclusions drawn based on p-values and test statistics.
