Answer: There are 24 people who can sample from one jar.
Explanation:
Since we have given that
Amount of jam a jar contains = 12 ounces
Sample size of an ounce is given by
![(1)/(2)\text{ of ounce}\\](https://img.qammunity.org/2019/formulas/mathematics/middle-school/9zt7crt22lxvo77hqpn1s34vqfhmvo0ju4.png)
So, Number of people can sample from one jar is given by
![(12)/((1)/(2))\\=12* 2\\=24](https://img.qammunity.org/2019/formulas/mathematics/middle-school/ebwbq56okxh36710bmaa4dp0jhijs5zaau.png)
So, there are 24 people who can sample from one jar.
