Recоrds suggest thаt cоаstаl plastic waste usually cоmes from five specific sectors in the following proportions: fishing - 15%, food packaging - 45%, agriculture - 5%, industry - 10%, and household goods - 25%. Environmental scientists collect 1,000 pieces of plastic debris from a coastline and categorize the source of the pollution. They found 185 pieces from fishing, 410 pieces from food packaging, 35 pieces from agriculture, 140 pieces from industry, and 230 pieces from household goods. Does the current plastic waste distribution match the historical trends? Sketch a well-labeled side-by-side bar graph that shows both the observed and the expected values for each category of the variable. Use graph paper, if possible. Show all the steps of the Chi-Square goodness of fit test: the null and alternate hypotheses, show the calculations to compute the test statistic, find the P-value (or the critical value), state the decision and explain why that is the correct decision (based either on the P-value or the critical value at the 0.05 level of significance), and write a conclusion in the context of the problem. In other words, explain what the results mean about the distribution of the categorical variable.
