The batteries of 150 MP3 players were tested to see if they were

defective. Of those batteries, 20 were defective. Estimate the
the population mean that a battery will be defective

The estimate of the population proportion of defective battery is 0.1333.

Step-by-step explanation:

Estimate of the population proportion of defective battery:

The estimate of the population proportion is the sample proportion.

Sample proportion:

Number of desired outcomes divided by the number of total outcomes.

Proportion of defective battery:

20 defective out of 150. Thus:

The estimate of the population proportion of defective battery is 0.1333.
