a) Determine the correlation coefficient between the high temperature and the number of cups of hot chocolate sold. (Round to the nearest thousandth as needed.) b) Determine whether a correlation exists at a=0.01. Since the value of the correlation coefficient is than the critical value of a linear correlation (Round to the nearest thousandth as needed.) c) Determine the equation of the line of best fit for the high temperature and number of cups of hot chocolate sold, yox. (Round to the nearest hundredth as needed.) d) Use the equation in part e) to estimate the number of cups of hot chocoiate sold if the dany high temperature is 30°F. The equation predicts that cups will be sold. (Round to the nearest whole number as needed.)
