A manager at a factory finds that in a random sample of 200 clocks, 15 are defective. What percent of the clocks are defective? Of the 10,000 clocks from which the sample was chosen, about how many clocks are probably not defective.

The next day the manager finds only 8 of the 200 randomly selected clocks are defective. About how many clocks out of the 10,000 produced that day are probably defective?​

Part A-7.5%

Part B-?

Part C-400 clocks

Step-by-step explanation:

part B-Use the sample ratio.-Multiply the sample ratio by the total number of clocks in the population.

Part C-Write a sample ratio.-Multiply the sample ratio by the total number of clocks in the population.
