Potatoes with a mass greater than 220 g are sold as baking potatoes. Find the percentage of the potatoes that are sold as baking potatoes.
The masses of 60 potatoes from variety B are measured as well. For variety B, the median is 175 g and the interquartile range is 30 g. Kali wants to buy potatoes whose masses vary less. Should she choose variety A or variety B? Explain how you decide.
Calculate an estimated mean mass.
A bag of potatoes has a mass of $2.5$ kg, correct to the nearest 100 g. Bags of potatoes are packed into a box. The mass of the box is 600 g, correct to the nearest 10 g. Calculate the upper bound of the total mass, in kilograms, of a box containing 10 of these bags of potatoes.
