Use it and Excel to answer this question. It contains the United States Census Bureau’s estimates for World Population from 1950 to 2014. You will find a column of dates and a column of data on the World Population for these years. Generate the time variable t. Then run a regression with the Population data as a dependent variable and time as the dependent variable. Have Excel report the residuals. (a) (4 marks) Based on the ANOVA table and t-statistics,...
Because the Florida manatee population is threatened, the Florida Maatee Sanctuary Act of 1978 was enacted to protect the species. Scientists interested in the relationship between the number of manatee deaths and time collected the data shown in the table.

~~~~~~~~~~~~TO BE COMPLETED USING RSTUDIO~~~~~~~~~~~~~~ ~~~~~~~~~~~~(Please display all RCode used)~~~~~~~~~~~~~~ Regression Is there a relationship between the number of stories a building has and its height? Some statisticians compiled data on a set of n = 60 buildings reported in the World Almanac. You will use the data set to decide whether height (in feet) can be predicted from the number of stories. (a) Load the data from buildings.txt. (Note that this is a text file, so use the appropriate...
2.5. Here are data on the number of people bitten by alligators in Florida over a 36-year period. Make two graphs of these data to illustrate why you should always make a time plot for data collected over time a) Make a histogram of the counts of people bitten by alligators. The distribution has an irregular shape What is the midpoint of the yearly counts of people bitten? b) Make a time plot. There is a great variation from year...
Oll prices have increased a great deal in the last decade. The following table shows the average oil price for each year since 1949. Many companies use oil products as a resource in their own business operations (like airline firms and manufacturers of plastic products). Managers of these firms will keep a close watch on how rising oil prices will impact their costs. The interest rate in the PV/FV equations can also be interpreted as a growth rate in sales,...
