📝 Answered - A company manufactures 2,000 units of its flagship product in a day. The quality control department takes a random sample of 40 units to test for quality. The product is put through a wear-and-tear test to determine the number of days it can last. If the product has a lifespan of less than 26 days, it is considered defective. The table gives the sample data that a quality control manager collected. | 39 | 31 | 38 | 40 | 29 | |---|---|---|---|---| | 32 | 33 | 39 | 35 | 32 | | 32 | 27 | 30 | 31 | 27 | | 30 | 29 | 34 | 36 | 25 | | 30 | 32 | 38 | 35 | 40 | | 29 | 32 | 31 | 26 | 26 | | 32 | 26 | 30 | 40 | 32 | | 39 | 37 | 25 | 29 | 34 | The point estimate of the population mean is $\square$ and the point estimate of the proportion of defective units is $\square$
