3. You are curious to investigate if the amount of sugars (in grams) is good predictor of the number of calories (Cal) in food. For that, you decide to do a linear regression analysis between the two parameters (sugars vs. calories). You are limited to only collect 10 sets of data (sugars vs calories per 100 grams of food) using the Nutrition Facts tables of 10 food items that you can find in grocery stores or online. Collect the information and record them in a table exactly like the table below. You MUST submit your raw data (the filled table) in an Excel file. Your solution to this question and the rest of the assignment must be submitted separately in a pdf file. Solutions in Excel will NOT be accepted, only raw data must be presented in Excel. Food item 1 2 3 4 5 6 7 8 9 10 Sugars (g) per 100 grams of the food Calories (Cal) per 100 grams of the food a) Comment on how you collected your data and mention how you ensured that your data set is random and unbiased. (4 marks) b) Using the collected information, conduct a simple linear regression experiment and find the regression line. (8 marks)
