An instructor is interested in finding out how the number of students absent on a given day is related to the mean temperature on that day. A random sample of 10 days was used for the study. The following data indicate the number of students absent (ABS) and the mean temperature (TEMP) for each day. |ABS 8 7 5 4 2 3 5n 50 45 6 55 58 TEMP 10 20 25 30 40 60 ) State the dependent (Y) variable and the independent (X) variable. (ii) Draw a scatter diagram of these data. (iii) Does the relationship between the variables appear to be linear or curvilinear? (iv) What is the logical explanation for the observed relationship?
