Neco 2024 Geography Question 9

The table gives the average monthly temperature (°C) and total rainfall (mm) for a coastal city over six months.\n\nMonth | Temp (°C) | Rainfall (mm)\nJan | 28 | 120\nFeb | 30 | 150\nMar | 32 | 200\nApr | 34 | 250\nMay | 33 | 230\nJun | 31 | 180\n\n(a) Calculate the Pearson correlation coefficient r between temperature and rainfall (round to three decimal places).\n(b) Determine the linear regression equation that predicts rainfall (R) from temperature (T) in the form R = a + bT (round a and b to two decimal places).\n(c) Using the regression equation, estimate the rainfall when the temperature is 35°C (round to the nearest mm).
