Assignment #1 Daniel Case INTRODUCTION Abalone populations are an economic and recreational resource that is threatened by a variety of factors, which include pollution, disease, loss of habitat, predation, commercial harvesting, sport fishing, and illegal harvesting. As a result of the aforementioned factors, abalone populations have declined considerably, pushing some abalone species to the verge of extinction. To help curb over harvesting and better protect abalone populations, it

The relationship between height and diameter of Limpet (Patella vulgata) shells and whether it differs between exposed and sheltered environments Abstract Limpets (Patella vulgate) live in algae rich environments on rocky shores. . It has been proposed that in more sheltered areas, limpet shells will grow to be flatter with a larger diameter, while in more exposed areas of coastline, they will grow a taller and narrower shell shape. To find out whether or not the shores of Aberdeen reflected this

2.2 Model A: p(x=1) = 1/4, p(x=2) = 1/4, p(x=3) = 1/4, p(x=4) = 1/4. This model is unbiased, in that every value has the same probability. Model B: p(x=1) = 1/10, p(x=2) = 2/10, p(x=3) = 3/10, p(x=4) = 4/10. This model is biased toward higher values of x. Model C: p(x=1) = 12/25, p(x=2) = 12/50, p(x=3) = 12/75, p(x=4) = 12/100. (Notice that the probabilities sum to 1.) This model is biased toward lower values of x. 2.3 The data are consistent with Model A, which predicts equal numbers

looking of sample date and probability to show us how reliable our inferences are. Our confidence interval will more times than not tell us what would occur if specific intervals were to occur, the larger the confidence interval the more likely the estimate is to be true. While a determined P value shows us how unlikely the observed outcome is. With these assumptions we can come to a null hypothesis which states that there is no significant difference Probability: ● Probability Models : ​There are various

cleaning the data, the first model was built using all the regressors under consideration. A thorough analysis of this full model, including residual analysis and multicollinearity check was done. The best subset regression was also tried. The normal probability
