4. A gas station monitors how many bags of ice they sell along With the maximum daily temperature for 100 days. A gas station data analyst plots the data in a scatterplot with temperature, in 0F, on the horizontal axis and the number of bags of ice sold on the vertical axis. She observes evidence of a linear relation- ship and calculates a correlation coefcient of 0.9952. The mean temperature is 84.12590F With a standard deviation of 9.61210F. The mean number of ice bags sold is 71.1173 with a standard deviation of 30.2413. (a) Determine the leastsquares regression line for this data, rounding to 2 decimal places. (b) Calculate R2 for this data and interpret What the value means. Round to 3 decimal places. (c) Predict how many bags of ice are sold When the temperature is 87.000F. Round to the nearest whole number
