Kindly provide the solution to the following questions in the picture provided bellow, in neat, clean and understandable way.

1. From a sample of n=15 readings on X = Traffic Volume (cars per hour) and Y = Carbon Monoxide Concentration taken at certain metropolitan air quality sampling site, we have these statistics: > x = 3 550 Zy = 167.8 Ex' = 974 450 Ey= = 1915.36 Exy = 41 945 (a) Compute the sample Correlation Coefficient r. (4 marks) (b) Test for Ho: p = 0 at the . 05 level of significance and state your conclusion in context of this problem (p is the Population Coefficient of Correlation). (4marks) 2. Using the data given in the table below X 2 6 co 9 Y 3 9 co 7 (a) Calculate the sample Correlation Coefficient r.(5marks) (b) Test for Ho: p = 0 at the . 05 level of significance and State your conclusion in context of this problem (p is the Population Coefficient of Correlation) ()
