Testing Manufacturer’s Claim on Toy’s Demands


Monsterz Toyz has developed a new action figure for boys that comes in six different colors. The manufacturer claims that the ratio of colors in each batch (in order from least to most popular) is 10% green, 10% red, 15% white, 20% yellow, 20% black and 25% blue. The last batch from the factory produced the following result:

Toy Color    Black    White    Blue    Red    Green    Yellow       
Count           72         77        80      61        72         38

    Hello Allison,I love the 2nd image that you did! I also, had never heard of SumoPaint, is something that I will have to exolpre a bit! I understand completely the 52 (or so) youtube videos that you probably watched. Sometimes they have what you want, sometimes they don't! However, it is always satisfying when you are able to produce something that you have taught yourself. Great job!Debra 0 likes
