1. A researcher is interested in knowing if there is a relationship between the alcohol content and the number of calories in a 12-ounce beer. To determine if there is relationship, a random sample was taken of beer's alcohol content and calories and the data recorded in the table below:

Alcohol Content (%)	Calories in12 oz
4.70	153
5.80	210
8.10	220
0.35	60
6.15	108
5.80	165
6.00	148
6.00	155
4.80	150
6.50	180

Using the data presented in the table:

1. Compute and interpret the correlation coefficient. [8 marks]
2. Compute and interpret the coefficient of determination. [2 marks]
3. Calculate and interpret the slope and y-intercept (constant term) for a regression line based on this data? [6 marks]
4. Estimate the number of calories in a 12oz beer when the alcohol content is 6.20%. [2 marks]
5. Explain the difference between the correlation coefficient and the coefficient of determination [2 marks]
