Roy's Toys received a shipment of 100,000 rubber duckies from the factory. The factory couldn't promise that
all rubber duckies are in perfect form, but they promised that the percentage of defective toys won't exceed
5%.
Roy wanted to get an estimation of the percentage of defective toys, and since he couldn't go over the entire
100.000 duckies, he took a random sample of 10 duckies. He found that 10% of them were defective.
What type of statistical study did Roy use?

Kevin has a spinner that has 10 equal sections and 2 sections of each color—red, blue, green, yellow, and purple. kevin spins the spinner 180 times. kevin determines about how many times the spinner will land on red or green, and his work is shown below. -kevin has the formula reversed; it should be the total number of sections over the number of red or green sections. -kevin should have used a 4 in the numerator because there are 2 red sections and 2 green sections. -kevin should multiply by the number of sections in the spinner rather than the total number of spins. -kevin calculated the prediction correctly and did not make any mistakes.
