While the average dog eats 900g of food a day (SD = 450), she monitored her dog for a month and found that her dog ate 1,100g of food a day (SD = 530). Can she conclude that her dog eats more than the average dog?
Standard Deviation we have a "standard"
way of knowing what is normal, and what is extra large or extra
small. Since her dog has SD of 530 compared to 450. So yes her dog eats more.
