1. You run a business that sells coffee. Create a monthly distribution of your revenue per month for the last two years. Bear in mind you only work for 1 week out of 4 in August and only for 2 weeks in December. 2. Calculate the mean and standard deviation for the data in task 1 . What does the standard deviation tell you about the data? 3. Convert the data in question 1 to quarterly (3-month period) revenue data. Then construct a histogram for this quarterly data in question. Explain/analyse the shape of the histogram. Are there any outliers? 4. Calculate the 5 points (the minimum, 25th percentile, 50th percentile, 75th percentile and maximum values) of the distribution. What do the values of C Q2 and Q3 tell you? Answer this question using the monthly (and the not the quarterly) datal Thanks. 5. Graph a boxplot based on your answer to question 4 . 6. Is the distribution of the monthly sales a normal one? Graph the frequency distribution curve by hand or with Excel. 7. Find the minimum level of sales that you are going to reach with 90% probability. 8. Now make a new monthly distribution of your number of customers for your coffee shop for the last 24 months. 9. Construct a scatterplot that relates sales to the number of customers per month in question 8 to the revenue per month that you produced in task 1 . 10. Find the correlation equation and the index of correlation. Draw any conclusions that you think can be drawn from the data. - You may want to include images/graphics etc. (for example from their website) to make your reasoning and argumention more visual and explicative - Font: Arial.
