To help determine how many soft drinks to stock the concession manager at York University Stadium wanted to know how the temperature affected soft drink sales. Accordingly, he took a sample of 5 games and recorded the number of soft drinks sold ($ hundreds) and the temperature (Celsius) in the middle of the game. These data and some relevant information are listed below. X = Temperature | y= Soft drink Sale 26 102.25 -5 25.65 Missing Data Value (find it) 70.26 -2 44.13 15 90.40 SUM | Ex = 42 Ey2 = 26169.0695, s2 = 160.30, JA= 66.5380 a) Calculate the mean of the temperature. b) Find the median of the temperature. c) Find the mode of the soft drink sale. d) Which data set (x - temperature or y = soft drink sale) has less relative variation? Justify your answer mathematically. e) Calculate the covariance. f) Calculate the coefficient of correlation and interpret its value
