Bear Manufacturing makes teddy bears on an assembly line $($the production numbers fall into a normal or bell$-$shaped curve$)$ and has found that the mean weight of the bears is $15$ ounces with a standard deviation of $0\mathrm{.}5$ ounces. These bears are sold to vendors of Wet Teddy Bear carts. The vendors have high standards for the consistency of the bears that they sell, so they will only accept teddy bears that weigh from $14$ ounces to $16$ ounces. If $20,000$ teddy bears were made on the assembly line during a week, then A teddy bears will be refused by the vendors that week.
