Since you have posted multiple sub-parts, we will solve the first three sub-parts for you. To get the remaining sub-parts kindly repost the complete question and mention the subparts that need to be solved. a) The temperature for different years from 1890 to 2020 is given in the table. Therefore, it can be said that the table shows the relationship between the year and the temperature. So, we are interested in studying the relationship between the year and temperature. How the temperature is dependent upon the year? How the temperature is changing for the given years? Therefore, the relationship between the year and the temperature has been studied. b) The two variables given are Year and Temperature. The dependent variable is the variable that depends upon another variable to predict its value.The independent variable is the variable that does not depend upon any variable for its value. It stands alone. Here, the year is the independent variable and temperature is the dependent variable. As the temperature is changing every year so it depends upon the independent variable year.c) It can be seen that the data is collected from the year 1890 to 2020 with an interval of 5 years. Total 27 data points are there which means the data was collected for 27 years. The total number of data points is 27. Yes, the sampling was conducted. The data is not collected for every year but proper samples are taken and data is recorded for those particular years. Proper systematic sampling was conducted.
